Horizontal waterfall chart on a dark navy background titled "How the world gained six years of life". Each row is a leading cause of death; each bar shows that cause's contribution to global life expectancy from 1990 to 2021, stacking cumulatively. Eight teal gain bars step right: enteric infections +1.12 years, lower respiratory infections +0.90, stroke +0.72, other communicable diseases +0.62, cancer +0.57, ischaemic heart disease +0.56, neonatal disorders +0.55, tuberculosis +0.52. A lavender bar rolls up ten smaller gains at +2.57 years. Two loss bars step back left: other pandemic-related mortality −0.52 (red) and COVID-19 −1.60 (orange). A final orange bar at the bottom shows the net change, +6.01 years, beside a large "+6.0 years of global life expectancy" callout. Source: IHME Global Burden of Disease Study 2021.
Monochrome dot grid on a dark navy background. Nine horizontal bands, one per species, each containing a number of small white dots equal to the surviving population. From top to bottom: Northern white rhino (2 dots, ringed in coral with an inline note "Both surviving rhinos are female · functional extinction is now arithmetic"), Vaquita (8), Hainan gibbon (37), Sumatran rhino (40), Javan rhino (50), Amur leopard (120), Cross River gorilla (250), Tapanuli orangutan (800), Mountain gorilla (1,063).

Line chart on a dark navy background titled "Five futures, one planet." World population from 1950 to 2100 in billions. A single white line shows observed history rising from 2.5 B in 1950 to 8.1 B in 2023. From 2023 the line splits into five projection paths: a coral UN WPP 2024 line peaking at 10.3 B around 2083 and ending at 10.2 B in 2100, surrounded by an 80 % and 95 % prediction-interval ribbon that fans outward; a blue IHME GBD 2020 line peaking earlier at 9.7 B in 2065 and falling to 8.8 B in 2100, with its own pale-blue 95 % uncertainty ribbon; three Wittgenstein SSP scenarios — green SSP1 declining to 8.0 B, yellow-green SSP2 ending at 9.9 B, and amber SSP3 still rising to 13.1 B at 2100. Each line is labelled at its 2100 endpoint with the model name and final value. The UN's 95 % prediction interval visibly brackets most of the disagreement between models. Sources noted at bottom: UN World Population Prospects 2024, IHME Vollset et al. 2020, and Wittgenstein Centre Data Explorer v3.

A white callout reads "Wright's Law (Swanson's Law for solar PV): every doubling of global solar capacity → ~20% cost decline. 1975 → 2024: Capacity ×3.4 million, Cost −99.8%." Drawn on a dark navy background.

Eight colored bands stack from polyethylene (cyan, bottom, 110 Mt in 2019) up through PP, Other, Fibres, PVC, PET, PS, and PUR (pink, top, 18 Mt). Total grows from 130 Mt to 460 Mt — a 3.5× increase. Each polymer is labeled in a ranked column on the right (PE 24% at top → PUR 4% at bottom), connected to its band by a colored leader line. A white callout notes that PE alone is 24% of all plastic produced and only ~9% of plastic waste ever gets recycled.

A raincloud plot on a dark background showing the distribution of TV episode ratings out of 10 for five shows: Breaking Bad, Succession, The Office, Game of Thrones, and The Simpsons. The y-axis lists each show with its total seasons and episode counts. Breaking Bad and Succession show tight, high-rated clusters between 8 and 10. Game of Thrones peaks high but shows a long tail of dots dropping down into the 5.0 range. The Simpsons displays the widest spread of ratings across the entire 5 to 10 scale.
A scatter plot titled "The Global Wealth Gap: Mean vs. Median" on a dark background. The x-axis shows median wealth per adult, and the y-axis shows mean wealth per adult, both in USD on logarithmic scales. Each dot represents one of 164 countries, color-coded by continent. A solid diagonal line represents "Absolute Equality" (1:1 ratio). Because no country is perfectly equal, all dots sit above this line. Additional dashed diagonal lines mark where mean wealth is 2x, 5x, or 10x higher than the median. Countries like Belgium, Australia, and Iceland cluster closer to the equality line, while countries like the United States, Russia, Brazil, and South Africa sit near the 5x and 10x lines, visually demonstrating extreme wealth concentration.
