A grid of small ridgeline plots titled "Measuring penguins". It compares ten body measurements across six penguin genera. The genera run down the rows: Aptenodytes, Eudyptes, Eudyptula, Megadyptes, Pygoscelis and Spheniscus. The ten measurements run across the columns: beak depth, beak length at the culmen and at the nares, beak width, first secondary length, hand-wing index, Kipp's distance, tail length, tarsus length and wing length. In each panel, three smoothed curves show how the measurements are distributed by sex, with females in red, males in orange and unknowns in blue, and a small triangle marks each penguin. Eudyptes and Pygoscelis have the fullest data across all three groups. Eudyptula, Megadyptes and Spheniscus have much less, often just a few birds of unknown sex. Aptenodytes, the largest penguins, sit furthest to the right on wing and tail length.
Generative art of a dense circular tangle of thin white lines on a dark charcoal background. Filaments grow outward from the center, wobbling and branching at sharp angles, crossing one another to form an intricate mesh of small angular shapes, like frost on glass or a lichen colony. The lines get finer and sparser toward the frayed outer edge, giving the disc a soft, bristly rim.
A diverging bar chart titled "Heavier hands, earlier nights", showing how every UFC fight since 1994 has ended, by weight division. Divisions are listed from lightest to heaviest in two groups, women's at the top and men's below. Bars grow to the left for fights that ended early, split into knockouts in red and submissions in blue, and to the right for fights that went to the judges, in beige. A white number on each red bar gives the division's knockout share, which climbs steadily with weight: from 14% in women's strawweight and 24% in men's flyweight to 45% in light heavyweight and 52% in heavyweight. Small colored numbers under each division name count its knockouts, submissions and decisions; men's lightweight has the most fights and women's featherweight by far the fewest.
A map titled "Shipwrecks off Ireland" showing the island of Ireland on a blue sea shaded by depth. Thousands of dark red dots mark recorded shipwrecks. They cluster most densely along the east and south coasts and in the north, thin out along the west coast, and continue as a sparse, widely spaced scatter far out into the Atlantic. A pale hatched band marks Ireland's maritime boundary, curving out to the west and south. The seas are labelled in italics: Atlantic Ocean to the west, Irish Sea to the east, Celtic Sea to the south. Ports are marked with star symbols and labelled: Dublin, Cork, Waterford, Shannon Foynes and Rosslare, with Derry (Foyle Port) and Greencastle in the north. A callout box in the lower right points to a wreck east of Dublin and reads: "RMS Leinster, 1918. Torpedoed by the German submarine UB-123, she sank with the loss of more than 500 of those aboard, the Irish Sea's worst single loss of life. The wreck now lies buried in sand about 25 metres down."
A tall chart on a cream background titled "Two Popes Named Leo, 135 Years Apart". Twenty words are drawn in a thin, wireframe-style display font and split into two color groups around a central zero line. At the top, in dark red, are words from Pope Leo XIII's 1891 encyclical Rerum Novarum: labor, nature, law, classes, rights, private, religion, property, authority and man's. These extend to the left. At the bottom, in dark teal, are words from Pope Leo XIV's 2026 encyclical Magnifica Humanitas: digital, ai, development, humanity, responsibility, economic, person, dignity, human and social. These extend to the right. Each word sits on the side of the encyclical that uses it more often, and its length shows how much larger that gap in frequency is, measured along a percentage axis at the bottom. "Labor" and "social" are the longest, the most lopsided words. Each group is labeled with its encyclical, pope and year.
A grid of twelve small charts on an off-white background, titled "Shifting names". Each chart is a UK first name given to both boys and girls. The names are Sacha, Nikita, Casey, Cody, Elisha, Brodie, Laurie, Rio, Remy, Shae, Brooklyn and Quinn. Within each, every horizontal bar is one year from 1997 at the top to 2024 at the bottom, split into orange for girls on the left and green for boys on the right, with a center line marking an even split. Small numbers where the colors meet give the counts in the first and last year. Nine of the twelve show orange at the top giving way to green toward the bottom, meaning they shifted from mostly girls to mostly boys, with Sacha the most extreme. Brooklyn and Shae make a U shape, starting orange, turning green in the middle, then returning to orange. Quinn runs the other way throughout, from green to orange.
Screen recording of an animated timeline titled "Video Game Films, 1993–2025" on a warm cream background. A horizontal gold timeline runs across the lower half. Film cards appear one at a time from left to right, advancing chronologically from Super Mario Bros. (1993) to A Minecraft Movie (2025). Each card shows the film's year and title, its worldwide box office and the multiple of its production budget, a blue bar sized to the gross, and its Rotten Tomatoes score with a coloured bar — red for rotten, amber for mixed, green for fresh. As each new card slides in, a film poster in a "now showing" frame at the top right crossfades to match it. The early titles skew red and low-grossing; the recent animated films (Sonic, The Super Mario Bros. Movie, A Minecraft Movie) show green scores and far taller box-office bars.
A horizontal diverging bar chart showing maternity leave before and after childbirth for 21 European countries in 2024. Each country has two bars extending from a central vertical line: blue-grey bars to the left show weeks before birth, orange bars to the right show weeks after. Within each bar, a crosshatch pattern marks the mandatory portion; the remaining outlined space is voluntary. Countries are sorted by total leave. Ireland is by far the longest at around 42 weeks total, with a large voluntary after-birth portion. Slovakia and Czechia follow at around 28 weeks each. The UK is the shortest at 2 weeks. Several countries, including Germany and Poland, have no before-birth leave at all. The chart title reads "Maternity leave in the EU, 2024".
A geographic grid map of the world where each country or territory is a row of coloured stripes, one per year, showing the share of final energy that came from traditional biomass from 1990 to 2010. Colour runs from dark purple for near zero to yellow for 100 percent. Most of Sub-Saharan Africa, South and South-East Asia are bright, with Ethiopia, Nepal and Nigeria among the highest, while Europe, North America and other rich countries stay dark purple at close to zero. A row of regional and income-group aggregates runs along the bottom: the World sits near 10 percent, low-income countries above half, and high-income countries near zero. The title reads "Renewable by necessity", and the subtitle explains that this reflects energy poverty rather than a green choice: traditional biomass is the fuel the poorest countries fall back on, and the fires degrade forests and produce smoke linked to millions of deaths a year.
A table titled "Research Nexus Readiness" showing Crossref metadata coverage for the top 20 countries by journal article DOI volume as of April 2026. Countries are grouped by world region and each row displays a country flag, country name, total DOI count in millions, and percentage of articles with references, abstract, an author ORCID ID, funding acknowledgment, funder ID, and license metadata. The percentage columns are shaded with a blue color scale, darker means higher coverage. The United States leads with 64.71 million DOIs. Stark differences are visible: reference coverage is generally high, while ORCID and license metadata rates are much lower across the board.
A dark, desaturated world map on a deep teal background. The continents are rendered in a muted dark tone with no colour. On the left, white text reads "Rio de Janeiro" in a large light-weight font, with "CITY OF FRIENDSHIPS" in small gold uppercase letters below. A faint gold downward arrow at the bottom left suggests scrolling.
A line chart titled "2.2 Million Cars" on a warm off-white background, showing Italian passenger car production from 1919 to 2024. Two lines: a dark navy area line from the Istat dataset covering the historical period from 1919, and a terracotta line from Wikipedia covering the more recent period to 2024. The chart peaks sharply in 1989 at 2.2 million units, then declines steeply. Key events are annotated with labels: Ferrari founded (1939), Italy enters WWII (1940), End of WWII (1945), Fiat 500 launched (1957), Lamborghini founded (1963), Oil crisis (1973), Lamborghini bankrupt (1978), Peak production 2.2M units (1989), Fiat Punto launched (1993), Lamborghini to VW (1998), Fiat: 90% of production (2001), Financial crisis (2008), Fiat Chrysler formed (2014), Stellantis formed (2021).

A horizontal bar chart titled "THE SUGAR WALL" on a light grey background, showing the highest import tax rate for each of the 24 HTS agricultural product categories entering the United States. Bars are sorted from shortest to longest. Most bars are slate blue; the Sugars bar is orange with an annotation reading "Sugar has a modest tax rate, but once the annual limit is hit, no more gets in." Tobacco has the longest bar at 350%, followed by Oil seeds at 164% and Vegetable & fruit preparations at 132%. Sugar sits near the lower middle at 12%. The x-axis is labelled "Highest import tax in the category (% of value)." Caption reads "Source: USITC Tariff Database · Graphic: Georgios Karamanis."

A horizontal bar chart titled "Boardings per km of service" with the subtitle "Swedish counties, public transport 2024". Each of Sweden's 21 counties is shown as a thick horizontal bar with the rounded value and county name displayed inline to the right. Stockholm stands out at the top with 5 boardings per offered kilometre, far ahead of Västra Götaland at 2.2 and Skåne at 1.6. Uppsala, highlighted in saffron, sits near the middle at 1.0. The remaining counties range from 0.9 down to 0.4, all shown in grey. Source: Trafikanalys.
A line chart titled "2 500 kr by 2050?" showing the Uppsala public transport monthly pass price from 2014 to 2050. Black dots mark observed annual prices, rising from 790 kr in 2014 to 1 150 kr in 2026. A log-linear trend line, solid through 2026 and dashed for the projection, follows the observed data closely and extends to around 2 500 kr by 2050. A widening confidence band shows increasing uncertainty further into the projection. Source: UNT, UL.
A bubble-line chart titled "The great Uppsala car swap" showing the share of new car registrations in Uppsala municipality by fuel type from 2013 to 2024. Three fuel categories are shown as lines with bubbles sized proportionally to annual registration volumes. Petrol and diesel vehicles (grey) dominated in 2013 at 96% of new registrations and declined steeply to 27% by 2024. Electric vehicles and plug-in hybrids (yellow) rose from under 1% in 2013 to a peak of 57% in 2023, settling at 53% in 2024. Hybrid vehicles (blue) grew modestly from 2% to 17% over the same period.

A line chart titled "Uppsala bus ticket prices" showing adult single-trip fares in Uppsala from 2010 to 2026 by payment type. Three lines are shown: the on-board fare (blue) starts at 30 kr in 2013 and rises to 42 kr by 2021–2023; the advance ticket fare (yellow) starts at 20 kr in 2010 and rises to 33 kr by 2021–2023; and the stored value fare (grey dotted line), covering värdekort and reskassa cards, starts at 16 kr in 2010 and reaches 26 kr in 2020 before being discontinued. From January 2024, a flat-fare 75-minute ticket replaced the previous structure, bringing all payment types to 39 kr in 2024–2025 and 40 kr in 2026. Source: UL, web.archive.org.
A half-eye plot titled "Parking spaces in Uppsala" with subtitle "Estimated mean and uncertainty, top 10 streets." Ten Uppsala streets are listed on the vertical axis, each paired with a saffron-coloured bell-shaped distribution showing the estimated mean number of parking spaces per street segment and the uncertainty around that estimate. Small grey tick marks below each distribution show individual observed segment counts. The horizontal axis is labelled "Number of parking spaces per street segment" and extends to 40. Råbyvägen, at the top, has the highest estimated mean at around 14 spaces per segment. Torgny Segerstedts allé, at the bottom, has the lowest estimated mean at around 1.2 spaces per segment.

A 2x2 grid of small multiple line charts titled "Europe's regions' response to COVID through preventive care spending" on a light grey background. Each quadrant covers one of the four European regions: Northern, Eastern, Western, and Southern Europe. Each region panel contains small charts for individual countries showing the year-on-year percentage point change in preventive care's share of current health expenditure, 2017 to 2023. Lines are coloured by region: blue for Northern Europe, terracotta for Eastern Europe, green for Western Europe, and ochre for Southern Europe, with other countries shown as muted grey lines. A sharp spike is visible in 2021 across most countries. Northern European countries such as Denmark, Estonia, and the United Kingdom show clear synchronised spikes and recoveries. In Eastern Europe, Czechia and Hungary spike sharply while Poland and Belarus barely move. Western Europe shows the largest spikes, led by Austria and the Netherlands. Southern Europe shows smaller and more varied responses, with Montenegro peaking in 2020 and Greece continuing to rise through 2022. The y-axis ranges from -5 to 7.5 percentage points.

A radial heatmap titled "Uppsala city bus punctuality" showing the percentage of city buses arriving on time each month across three years. Three concentric rings represent 2023 (inner), 2024 (middle), and 2025 (outer), each divided into 12 monthly segments. Segments are colored on a scale from amber (lower punctuality, 86–89%) to indigo (higher punctuality, 95–98%). Season labels, Winter, Spring, Summer, and Autumn, appear around the outside of the chart with bracket guides. July consistently shows high punctuality across all years, with July 2025 reaching 97.6%. December 2023 has the lowest punctuality in the dataset at 87.96%. Winter months show the most variation across years, while summer months cluster toward the high end. Source: UL.
A dice plot titled "Uppsala's new cars by season" showing a 4×4 grid of die faces. Rows represent four fuel types: Petrol/Diesel, Hybrid, Plug-in Hybrid, and Battery Electric. Columns represent the years 2015, 2018, 2021, and 2024. Each die face contains four pips positioned at the corners: green for spring (top left), orange for summer (top right), brown for autumn (bottom left), and blue for winter (bottom right). Pip size reflects each combination's share of all new car registrations in Uppsala that year. Petrol/Diesel dominates 2015 and 2018 with large pips across all seasons, then shrinks noticeably by 2021 and 2024. Battery Electric pips are barely visible in 2015 but grow substantially by 2024, with autumn the strongest season. Plug-in Hybrid pips grow from 2015 to 2021 then shrink in 2024. Hybrid remains relatively small throughout. Made with ggdiceplot. Source: SCB Statistikdatabasen.
A line chart titled "Uppsala keeps cycling" with subtitle "Total cycling network length". Two lines show the total length of the cycling network from 2015 to 2024: the Municipality line in saffron and the Urban area line in indigo. The municipality network grew from 513 km in 2015 to 569 km in 2024, a gain of 56 km annotated in bold saffron text. The urban area network grew from 432 km to 468 km, a gain of 36 km annotated in indigo. Both lines rise steadily with no major dips. Source: Uppsala Miljöbarometern.
A line chart titled "Going electric" with subtitle "EV and plug-in hybrid share of new cars". Four lines trace the share of new car sales that are electric or plug-in hybrid from 2010 onwards. Uppsala (saffron) and Sweden (indigo) rise steeply together, reaching 59.6% by 2025 and 58.0% by 2024 respectively. World (light grey) and EU (dark grey) also grow but reach only 22.0% and 21.0% by 2024. All four lines show low shares until around 2018, then accelerate sharply.

A line chart titled "Kids go their own way" showing the share of school journeys by transport mode across grades F-class to Year 6 in Uppsala municipality, 2021. Four lines track car, public transit, cycling, and walking. Car starts at 36% in F-class and falls steadily to 11% by Year 6. Public transit starts at 7% and rises to 27% by Year 6, dipping to 15% at Year 5 before jumping. Cycling remains relatively stable between 27% and 33%. Walking rises from 26% to a peak of 40% at Year 5 before dropping to 30% at Year 6. The lines for car and transit cross in the middle grades, making the shift from car dependency towards independent travel clear. Source: Uppsala kommun, guardian survey.
A line chart titled "Bonus-malus effect?" showing new EV and plug-in hybrid car registrations per 10,000 residents in Uppsala municipality from 2010 to 2024. The line hovers near zero until around 2013, then climbs slowly before accelerating sharply from 2018, when Sweden's bonus-malus policy introduced rebates for EVs and taxes on high-emission cars, highlighted by a blue-grey shaded band. Registrations peak at roughly 110 per 10,000 residents in 2022–2023, then fall back to around 80 in 2024 after the bonus was removed, leaving only the malus tax on high-emission cars, marked by a pale amber band.

A scatter plot titled "A seasonal pattern" showing the relationship between average monthly temperature and Uppsala city bus ridership for 2024 and 2025. The x-axis runs from about −5°C to 20°C and the y-axis from roughly 1.2 million to 2.8 million monthly trips. A grey regression line slopes downward from upper left to lower right, indicating a negative correlation. Points are labeled with three-letter month abbreviations and colored by year: indigo for 2024 and amber for 2025. Cold winter months such as January and February cluster in the upper left with the highest ridership, while warm summer months, particularly July, which sits at around 20°C and below 1.5 million trips, fall at the lower right. The two years follow a very similar pattern. Source: UL Statistik and SMHI Open Data.
A circle packing chart titled "Goods on the move" showing road freight loaded in Uppsala County by goods type in 2024, measured in thousand tonnes. Circles are color-coded by three categories shown in a top legend: amber for Logistics and mixed, indigo for Manufactured, and near-black for Raw and natural. The largest circle by far is Mining and quarrying at 3,215 thousand tonnes, in near-black. The next largest are Food and beverages at 1,329 (indigo), Removals and miscellaneous at 1,310 (amber), and Agriculture and fish at 1,233 (near-black).

A bubble chart titled "Kids go their own way" with the subtitle "Share of journeys by mode and grade in Uppsala, 2021." The chart shows four transport modes, car, public transit, cycling, and walk, as columns, with school grades F-class through Year 6 as rows. Each cell contains a circle whose size and labelled percentage represent the share of journeys for that mode and grade. Car use (indigo circles) falls steadily from 36% in F-class to 11% by Year 6. Public transit use (amber circles) rises from 7% to 27% over the same range. Cycling (near-black circles) stays relatively stable between 27% and 33%. Walking (grey circles) peaks at 40% in Year 5 and drops to 30% in Year 6. The data come from a guardian survey of over 7,400 households. Source: Uppsala kommun, guardian survey.
A small-multiple slope chart titled "Riding Uppsala" with the subtitle "Bus journeys declined in 2025." The chart contains twelve facets, one per calendar month, each showing an arrow from 2024 to 2025 representing the number of city bus trips made on UL (Upplands Lokaltrafik) in Uppsala. Amber arrows indicate months where ridership fell; indigo arrows indicate months where it rose. Ten of the twelve months saw declines: January dropped from 2.7 million to 2.5 million trips, February from 2.7 million to 2.4 million, and April had the steepest fall, from 2.7 million to 2.1 million. Only March and May showed marginal increases. Summer months have the lowest ridership overall, with July falling from 1.5 million to 1.3 million. Source: UL.
A grid of nine small charts on a warm off-white background titled "Are older things harder to fix?" Each panel shows smoothed repairability scores on the y-axis against item age at the time of repair on the x-axis, with the scale reversed so older items (up to 100 years) are on the left and newer items on the right. Lines are colored amber for electric and green for non-electric items. Panels are faceted by category: Bicycles, Clocks and alarm clocks, Computer equipment and phones, Display and sound equipment, Household appliances, Jewelry, Textile, Tools, and Toys. In household appliances, tools, and toys, the amber and green lines cross over across the age range. Clocks, textiles, and display and sound equipment show lower repairability scores among older items. Bicycles, computers and phones, and jewelry show little variation across the age range. Caption reads "Source: RepairMonitor · Graphic: Georgios Karamanis."
A scatter plot titled "Wheels & wealth in Uppsala..." with the subtitle "...mostly correlate, except for one district." The x-axis shows median net income in thousand kronor and the y-axis shows cars in use per capita. Each point represents one of Uppsala's residential districts, sized by population and coloured in indigo blue. The overall trend is positive, higher-income districts tend to have more cars per capita. Four groups are highlighted with amber hulls: "Student areas" (Studentstaden and Västra Flogsta) sit at low income and low car ownership; "6 peripheral areas" (Stadens omland) cluster in the mid-to-high income and mid-to-high ownership range; "Highest income" (Gamla Gottsunda-Vårdsätra-Vreta) is at the far right with high income but moderate ownership; and "Kåbo-Norra Rosendal" is the clear outlier with middle income but by far the highest cars per capita at around 0.85, well above the trend.

A radial bar chart titled "Uppsala's bus clock" with the subtitle "Departures per hour, weekday vs weekend." Hours of the day (0:00 to 23:00) are arranged clockwise around a circle. For each hour, two bars extend outward: orange for weekday and blue for weekend departures. Weekday bars are substantially longer, peaking at 7:00 with 3,145 average departures, with a second peak at 15:00 (3,120). The overnight trough bottoms out at 2:00 with 56 departures. Weekend bars are much shorter and more evenly distributed, peaking mid-morning around 10:00–11:00 with around 680 departures and dropping to 56 at 4:00. Source: UL GTFS data, 4–30 April 2026.
A two-panel chart titled "Uppsala emissions down" with the subtitle "Change in total and breakdown by sector." The upper panel is a line chart showing the percentage change in Uppsala's total greenhouse gas emissions relative to 1990, from 1990 to around 2023. Emissions rose slightly through the 2000s before falling sharply, reaching −44% by 2023. The lower panel is a stacked area chart showing absolute emissions in kilotons by sector over the same period. At its peak around 2010, total emissions were close to 1100 kt and almost halved by 2023 to 550 kt. Electricity and heat (orange) is the largest sector and has declined the most; Transport (indigo), Agriculture (grey), and Other (light grey) make up the rest.

An experimental chart titled "Cold months fill the buses" with the subtitle "Bus ridership vs. temperature in Uppsala." Twelve center-aligned bars, one per month, are stacked vertically and arranged so the year wraps from June at the top through January in the middle to July at the bottom. Because the bars extend symmetrically from a central axis rather than from a baseline, the chart forms a leaf-like silhouette. Bar length encodes monthly bus ridership and bar color encodes average temperature: orange for warm months and indigo-blue for cold ones. Winter months such as January are longer, showing that Uppsala residents ride the bus more when it is cold. Source: UL and SMHI, 2024–2025 averages
A slope chart titled "Uppsala trains on track" with the subtitle "More running, more on time." Two lines connect 2024 and 2025.

map of Norway with circles marking 11 salmon farming production areas along the coast. The sea is deep blue, Norway is near white, and the neighboring countries are a soft warm grey. Each circle sits on its production zone. Bigger circles mean higher average monthly mortality from 2020 to 2025. Red circles are zones where the mortality rate rose between 2020 to 2022 and 2023 to 2025; blue circles are zones where it fell. Each is labeled with its percentage change. Central Norway has the most red: Nordmøre and S. Trøndelag up 33%, Stadt and Hustadvika up 23%, N. Trøndelag and Bindal up 21%. In the south, Nordhordland and Stadt fell 15% and Skagerrak and Ryfylke fell 13%. In the far north, Kvænangen–Loppa and Finnmark both fell 22%. A text box in the lower right explains the chart.
Three Sims 4 Studio windows showing custom content in progress: a baby Sim wearing a grey onesie printed with the “future R superstar” aardvark design (by Allison Horst and David Keyes); a poster of Florence Nightingale’s rose diagram of causes of army mortality; and a poster of Fernanda Viégas and Martin Wattenberg’s wind map of the United States.
Three stacked bar charts showing the distribution of probability estimates for "Highly Likely" (green) and "Highly Unlikely" (orange) across three groups of English speakers. The x-axis runs from 0 to 100%. For native English speakers (top panel), estimates for "Highly Likely" cluster around 80–95% and for "Highly Unlikely" around 1–10%, with considerable spread across the range. The fluent non-native panel (middle) shows a similar pattern. The non-fluent panel (bottom) is more concentrated at the extremes, with no responses in the middle range. Color intensity represents the proportion of responses within each group.
A screenshot from Sims 4 Studio showing a custom blue t-shirt with a large ggplot2 hex sticker logo on the chest, alongside a framed version of Minard’s chart (the famous visualization of Napoleon’s 1812 Russian campaign) displayed as a wall painting in the object preview window.
A connected scatterplot showing the relationship between the male-to-female ratio and mean female body condition index on the Golem Grad Island plateau from 2008 to 2023. The x-axis shows males per female from capture surveys, ranging from around 16 to 93. The y-axis shows mean female body condition index, ranging from about 4.9 to 6.8. Points are sized by the number of females captured that year. The path moves generally rightward and downward over time, showing that as males increasingly outnumber females, female body condition declines. Five years are annotated: 2008 (study begins, 52 males per female), 2009 (most females captured, 30 females and 19 males per female), 2013 (only 2 females captured, 93 males per female, lowest BCI), 2020 (highest recorded female BCI), and 2023 (last survey year, with a demographic prediction that the last island female will die in 2083).
A horizontal bar chart showing total Science Foundation Ireland grant funding per year from 2005 to 2024. Each bar contains the top 3 most distinctive words from proposal titles that year, ranked by TF-IDF, with superscript numbers indicating how many proposals used each word. Notable years include 2019 (peak funding), 2020 (covid, 19, sars), and 2013 (erc, funds, isca).
An animated visualization with three gauge panels tracking New Zealand sheep numbers, human population, and sheep-to-people ratio from 1960 to 2024. Sheep (green) peaked at over 70 million; the ratio (blue) ranged from 22.4 down to 4.4 sheep per person; people (orange) grew steadily throughout.
A map of Italy with eight highlighted regions hosting 2026 Winter Olympics venues. Eight cities are labeled and connected with accent-colored lines. Detailed regional maps show venue locations with medal event counts in labeled boxes. Subtle elevation relief rendered as alpha transparency reveals topography across all maps.
A faceted tile plot with 18 edible plants, each name drawn in chunky bitmap font. Colored tiles stretch across the temperature range in degrees Celsius for each plant, with the minimum and maximum values labeled. Cultivation type sits just below the plant name. The plot shows how growing temperature ranges vary from plant to plant.
Stacked bar chart showing the distribution of Brazilian companies by owner qualification and company size. Bars are sized by log-scaled total counts, with three categories: micro-enterprises, small-enterprises, and other. Owner qualifications are ordered from those with the highest to lowest proportion of micro-enterprises.
Network visualization showing the most frequently mentioned word stems in NASA's Astronomy Picture of the Day descriptions. Each large star represents a word, sized by frequency and grouped around the central concept it relates to (shown as small gold points). The most common words are words related to stars, light, image and galaxy.
Composite visualization showing Africa's linguistic diversity. Left: Treemap showing African languages sized by number of native speakers and colored by language family. Right: Geofaceted map of African countries showing the main languages in each country, also colored by language family. Niger–Congo (435 million native speakers, 377 languages), Afroasiatic (333 million speakers, 21 languages), and Nilo-Saharan (44 million, 69 languages) are the largest language families. Most African countries are multilingual and the 'main' language is often just one among many.
Waffle chart showing James Bond's weekly alcohol consumption across 12 novels. Each gold square represents one unit of alcohol. The chart is faceted by book title and year of publication, with consumption rates ranging from 52.4 units per week (Goldfinger) to 132 units per week (You Only Live Twice). Numbers labelled on each facet show the weekly consumption total.
