Scatter chart titled "Pi Filling" showing the first hundred digits of pi. Each digit (0–9) is plotted at its position along the x-axis and its value on the y-axis, with points colored by digit and sized by how often that digit appears in the first million digits of pi. All ten digits are nearly equally distributed in the full million, ranging from about 99,548 occurrences (digit 6) to 100,359 (digit 5). The points are scattered across all digit values with no discernible pattern, reflecting pi's apparent randomness.
Line chart titled ‘The Optimism of Youth’ comparing median assigned probabilities for 19 common phrases between respondents under 18 and those 75 or older. Phrases are ordered from lowest to highest probability. Across most of the range, under-18s assign higher probabilities than those 75+—for example, ‘Unlikely’ is 12% for the older group vs. 20% for younger, and ‘Realistic Possibility’ is 60% vs. 70%. The two groups converge at the extremes (‘Almost No Chance’ is 4–5% for both; ‘Will Happen’ is 100% for both) and in parts of the middle range (‘Might Happen’ and ‘About Even’ are 40% and 50% respectively for both). One exception stands out: ‘Probable’ is assigned 75% by those 75+ but only 70% by under-18s.
Stacked column chart titled 'Hormone Imbalance' showing male vs. female tortoise recaptures on the Golem Grad island plateau from 2008 to 2023. Males vastly outnumber females every year, with male counts ranging from 163 to 956 while female counts stay between 2 and 33. The highest totals occurred in 2011 with 956 males and in 2016–2017 with around 800 males each year. Males comprise over 90% of recaptures throughout the study period.
Sankey diagram titled 'Follow the Money' showing grant commitments from Science Foundation Ireland's top 10 programs to research institutions from 2000 to 2024. The Research Centres Programme dominates with €991M in commitments, followed by the Principal Investigator Programme at €594M. Trinity College Dublin is the largest recipient overall, receiving major funding from nearly all programs, followed by University College Dublin and University of Galway. Other significant recipients include University College Cork, University of Limerick, and Tyndall National Institute. The diagram reveals heavy concentration of funding among traditional universities, with smaller allocations to technological universities and research institutes.
Time-series line chart titled 'The Rise and Fall of the Sheep' showing population of New Zealand livestock from 1935 to 2024. Sheep dominated throughout, peaking near 70 million in the early 1980s before declining steadily to about 24 million by 2024. Cattle remained relatively stable between 8-10 million from 1971 onward. Poultry data begins in 2002 at around 22 million and stays fairly consistent near 25 million. Pigs remained the smallest population, fluctuating between 250,000 and 550,000 throughout the recorded period.
Stacked bar chart titled "Cold Play" showing the number of 2026 Winter Olympics events by discipline. Curling leads with 436 total events, almost entirely non-medal events. Freestyle Skiing (222) and Snowboard (192) follow with mostly non-medal and medal events. Sliding sports like Bobsleigh, Luge, and Skeleton have significant training events alongside their competition schedules—Bobsleigh has 72 training events, Luge has 70, and Skeleton has 36. Speed Skating and Cross-Country Skiing are medal-heavy with 42 and 35 medal events respectively. Biathlon is unique with only medal events (33). The chart reveals how different winter sports balance training, qualifying, and medal events during the Games.
Scatter plot titled 'Long-Term Investments' showing energy value of 12 edible plants compared to days to harvest and minimum growing temperature. Bubble size represents energy in kcal per 100g raw, with color indicating water requirements from very high to very low. Most plants cluster between 40-70 days to harvest and 7-17°C. Broad beans offer the highest energy return (88 kcal) with very low water needs at 85 days. Peas provide 80 kcal but require very high water. Brussels sprouts are an outlier requiring 180 days to harvest for only 35 kcal. Lower water requirement plants like kale and broad beans tend toward longer harvest times.
Sankey diagram showing the breakdown of Brazilian companies by size and legal category. Brazil's roughly 141,000 companies split into three size groups: Micro enterprise (66,000), Other (42,500), and Small enterprise (32,600). From each size group, flows branch into legal categories. LLCs dominate across all sizes, accounting for about 120,000 companies total. Sole Proprietorships are the next largest category at around 15,000, concentrated heavily in Micro enterprises. Partnerships and Privately Held Corporations appear mainly in the Other size category, with smaller numbers elsewhere. Cooperatives, Publicly Traded Corporations, and State-Owned Enterprises make up a very small share.
A dot chart titled “Al-doption Curve” and subtitled “Al-assisted commits and PRs since May 2025 adoption”, showing dots for pull requests increasing steadily from May to 22 in December, and dots for commits increasing slowly until September and then steeply from October to December, where they reach 53.
Bar chart titled “The Grain Divide” showing the predominance of flour/wheat-based versus rice-based recipes across 49 cuisines. Cuisines are listed vertically from Austrian at the top to Thai at the bottom. Bars extend either right (indicating flour/wheat predominance, marked with a bread emoji) or left (indicating rice predominance, marked with a rice bowl emoji) from a central vertical axis. European cuisines like Austrian, Dutch, and Finnish have the longest bars extending far right into the bread zone, while Asian cuisines like Thai, Vietnamese, and Chinese have bars extending left into the rice zone. The chart uses a dark background with green-tinted bars, creating a diverging bar chart that clearly shows the grain divide between Western and Eastern cuisines.
Sankey diagram titled 'Oyster Quotient: Visa requirements to and from United States' showing the flow of visa requirements between the United States and other countries. On the left side, the largest flow shows 'Visa Required' for foreign nationals traveling to the US, while on the right side, the largest flow shows 'Visa-free Access' for US citizens traveling abroad. Other categories include Electronic Travel Authorization, Online Visa, and Visa on Arrival options. The visualization illustrates the asymmetric nature of visa requirements, where most foreign nationals need visas to enter the US, but US citizens enjoy visa-free access to most international destinations.
