Scatter plot showing analysis of 1,041 terminated NSF grants totaling $613.26M, representing 1293.5 years of lost research time. The visualization is divided into four quadrants showing different grant clusters: Early-stage Mega Grants (51 grants, 66% complete, 547 days left), Early-stage High-value Grants (382 grants, 81% complete, 236 days left), Late-stage High-value Grants (353 grants, 32% complete, 865 days left), and Late-stage Mid-value Grants (255 grants, 86% complete, 192 days left). Each cluster is represented in a different color (orange, teal, purple, and pink), with point size indicating days remaining. The y-axis shows the funding amount on a logarithmic scale, and the x-axis shows the percentage of grants completed.

A map showing uncertainty in Alaska glacier measurements. Three distinct regions of glaciers are labeled, with colors ranging from yellow (low uncertainty) to purple (high uncertainty). An information box explains that uncertainty is affected by distance from observation points, glacier size, and remote locations. The visualization has the distinctive yellow border of National Geographic style.

Topic-Speaker Bipartite Network for useR! 2025 Conference. The visualization shows connections between speakers (salmon-colored circles) and five topics (blue circles with labels): Visualization, Machine Learning, Data Wrangling, Package Development, and Reproducibility. The network clusters speakers around their respective topics, with some speakers positioned between multiple topics, indicating cross-disciplinary interests. The layout places topics centrally, with speakers radiating outward, creating a star-like pattern for each topic cluster.

A dot plot showing the gender gap in educational exclusion across regions. Sub-Saharan Africa has the largest gap (+8.2%) where females have less education, followed by Central and Southern Asia (+4.6%) and Northern Africa (+2.9%). Europe and Eastern Asia show minimal differences. Latin America (-0.3%) and Oceania (-0.5%) have slightly more males with less education. Error bars indicate statistical uncertainty. A dashed vertical line represents gender parity, with subtle background shading distinguishing areas where females (pink) or males (blue) are more excluded.

A dot plot showing cardiovascular disease prevalence across U.S. states and territories with 95% confidence intervals. States are ordered vertically from highest to lowest prevalence (West Virginia at 6.7% to Virgin Islands at 1.4%). Each state/territory has a dot showing its estimate and a horizontal line extending from the dot showing the confidence interval range. A vertical dashed line marks the national median of 4.0%. The visualization demonstrates how statistical uncertainty varies, with some regions having wider confidence intervals than others.

NBA Team Risk Matrix visualization showing team performance uncertainty vs. win percentage for 2023-24 season. Teams are plotted in four quadrants: high-risk/unpredictable (upper left), good but unpredictable (upper right), consistently poor (lower left), and consistently good (lower right). Teams are color-coded by point differential (red=negative, blue=positive) with circle size representing blowout risk. Dallas shows the highest variability, while Boston has the best performance.

Time series line chart (1990-2022) showing gender differences in diabetes prevalence across regions. Europe shows men have nearly 40% higher rates than women (positive values). Africa shows women historically had up to 20% higher rates than men (negative values), though this gap has narrowed. Asia shows minimal gender differences, while Oceania and Americas show moderate differences with women having slightly higher rates.

Line chart showing pharmaceutical giants' stock performance from 2018-2025 on a logarithmic scale. The chart displays five companies (LLY, ABBV, MRK, BMY, PFE) with Eli Lilly (LLY) showing the strongest growth, reaching nearly $1,000 by 2025. The COVID-19 pandemic period is highlighted with a pink vertical band in 2020. All companies experienced volatility during this time, with different recovery patterns afterward.

Time series visualization of Hubble Space Telescope observations from 2016-2024, showing the 10 most frequently observed celestial targets. Gold dots represent observations, with NGC104-WFC having the most consistent observations over time. M-51 shows a concentrated period of observations in 2017-2018, while NGC5139-WFC observations only begin around 2020.

Two plots entitled Daily Mean Fatality Count, 1992-2016, and Daily Mean Fatality Count in April, 1992-2016. The top plot shows fatalities on the y-axis, and day of year on the x-axis. April 20 is marked with a dashed line, and does not appear to be significantly higher than other days of the year. Fatalities are much higher on January 1st, and generally higher in the months following April than at the beginning of the year. The second plot shows fatalities by day of the year within the month of April. The 20th (day 110 in the year) is approximately in the middle of fatality counts for April. Error bars on both plots are noted as representing 95% bootstrapped confidence intervals. Both plots were generated using code provided by @Rmadillo on GitHub.

Line graph showing the rise and fall of trilobite fossils over time (540-250 million years ago). The data peaks in the Ordovician period around 480-450 Ma, then sharply declines after the Ordovician Extinction (444 Ma), continues at lower levels through the Silurian period, and diminishes further after the Devonian Extinction (372 Ma).

Bar chart showing the difference between April 20th fatal crashes and yearly averages from 1992 to 2016. Orange bars represent years above average (9 years total), with 2007 showing the highest peak at +57. Blue bars represent years below average (16 years total), with 2004's lowest point at -60. The visualization suggests no consistent pattern of increased crashes on April 20th compared to yearly averages.

A faceted area chart titled 'The Shifting Speeds of Urbanization (1960-2023)' showing annual percentage point changes in urban population for eight countries. Countries are arranged by their maximum rate of urbanization, with Japan exhibiting the highest spike (over 1.5%) around 2000, followed by China, which has sustained high rates, and Brazil, which experienced early high rates that gradually decreased. Nigeria, India, Egypt, the United States, and Germany show more moderate urbanization rates. Negative urbanization periods are indicated in orange for countries such as China, Egypt, and Germany.
