Small multiples slope chart of Reporters Without Borders Press Freedom Index scores for African countries, comparing 2025 to 2026. A table at the bottom right of the chart shows that only 24 (45.3%) of 53 countries showed improvement compared to 2025, the score remained the same as in 2025 for 7 (13.2%) countries, and the score decreased for 22 (41.5%) countries.
Bubble chart showing Plasmodium vivax malaria parasite rate (PR) from surveys reported in the Malaria Atlas Project across 21 Asian countries from 1985 to 2018.

Line chart showing trends in overweight and stunting prevalence among children under 5 from 2000 to 2024, split horizontally into four panels by country income group (from left to right: high, upper middle, lower middle, and low income) and vertically into overweight on top and stunting below. Overweight prevalence (top row, grey) remain low across all income groups with a slight upward trend. Stunting prevalence (bottom row, red) are much higher in lower middle and low income countries but have declined substantially over the period. Each panel shows individual country lines in the background and a bold line representing the group average.
Dumbbell plot comparing insecticide-treated net (ITN) access and use across 40 African countries in 2024, ordered by use rate. Each country has two dots connected by a line (blue for use and red for brown). Countries at the top such as Burkina Faso, Gambia, Niger and Malawi have the highest use rates (above 96.5%), while Ethiopia, Nigeria, and Eritrea have the lowest (lower than 73%).

A faceted line chart showing the sex ratio of Hermann's tortoises across three locations (Beach, Konjsko, and Plateau) on Golem Grad island in North Macedonia from 2008 to 2023. The Plateau (right most) panel shows consistently high male bias, peaking around 93 males for every female around 2013 before declining to around 16 by 2023, but remaining heavily male-biased throughout. Beach (left most panel) shows moderate male bias with high variability. Konjsko (middle panel) mostly dips below the parity line into female-biased territory, shown by a shaded region. A dark dashed horizontal line marks the 1:1 sex ratio across all panels. The y-axis is on a log10 scale.
Beeswarm plot showing the number of grants awarded by Science Foundation Ireland across three decades (2000s, 2010s, 2020s), grouped by funding programme, and with the total funding committed as point size. The Research Frontiers Programme dominated the 2000s with 763 grants. In the 2010s, the Technology Innovation Development Award (496) and Conferences and Workshops Programme (434) were the largest. By the 2020s, the Discover Programme and Frontiers for the Future led, each with 393 and 321 grants respectively. Most other programmes across all decades awarded fewer than 150 grants. The programmes with the highest number of grants are not necessarily those with the greatest funding committed.
