The rise of larger vehicles like SUVs and pickup trucks, with their taller hoods and larger blind zones, has contributed to a 75% increase in pedestrian and cyclist deaths since 2009. Until we design better streets and ban these vehicles, people outside these vehicles will keep dying.

The vehicles on American roads have grown larger — and they are killing thousands more pedestrians, a Times investigation found.

After 18 months of R&D with a team of specialist academics, I'm VERY excited to say that @carbonbrief.org has just launched 'Project Cosmos'... ...the world's largest database of climate research Our hope is this becomes a major new resource interactive.carbonbrief.org/cosmos/index...

🗺️ 📣 I've been off bluesky for a while, but popping in to announce Graticule, my new app for making maps! graticule.org It's a work-in-progress but I'd love to hear any feedback. What features would you like to see next?
Whichever of the purple dots you look at turns more purple.
What about a straight line that bends when the circles get closer and stretches when they get farther. It's surely not possible using pure CSS, right? Right!? 👀 css-tip.com/bending-line/ Probably my new favorite demo, powered by the modern features. CSS is awesome! 😍
CSS by T. Afif@css-only.dev · 2mo ago💡 CSS Tip! Connecting two circles with a curved line using only CSS? Yes, it's possible! 🤩 css-tip.com/connected-ci... A demo powered by the future of CSS (border-shape, if(), anchor position, etc). Update your Chrome and play with it! Stay tuned for more complex connections 👀
I’m finally wrapping up the #30DayChartChallenge. I managed to create 11 visuals (not 30 but more than I ever did). I mostly wanted to uplevel my #Svelte + #D3 skills for interactive charts. Of course I used AI, but mostly as a coding buddy not for vibe coding. Link to project below 👇
Accessing cash is getting harder. The number of ATMs has declined substantially in almost all Local Authorities in England in the past five years. Across the UK ATM numbers have fallen continuously since 2015. 💷 📉 One last #Dataviz for #30DayChartChallenge Day 11 | Physical. Made in Svelte + D3
This is one of the cooler uses of a pie chart I've seen in the wild. It's like that sky/pyramid illusion, but with real data! S/O to Ceren Dolma @datawrapper.de for this clever #dataviz! www.datawrapper.de/blog/twiligh...
In this notebook, @laotzunami.bsky.social visualizes a state space of possible chart types and transitions among them along defined edges. Transitions between unconnected types are achieved by routing through intermediate types. observablehq.com/d/3c8b082818...
The local elections in one chart. Labour has been squeezed between the Greens in young wards and Reform in older working-class wards www.economist.com/britain/2026...
#30DayChartChallenge Day 10 | Pop Culture. Top 20 books of 2025 by genre & publish date, according to Readers’ favourites on Goodreads. 📚📖 Most romance novels were published in spring/summer. Nonfiction books have the longest book titles and Fantasy books lead in terms of total pages. #Dataviz
April might be over, but I still got a loot of gaps to fill. #Dataviz for #30DayChartChallenge Day9 - Wealth. Who has savings? 💷💷💷 Young people are least likely to have a lot of savings. But even as people age, there's still a notable proportion of older people who have very little.
On my way to #EGU26, perfect time to drop a new post! 🗺️ Something I've been wanting to write about: Mercator projections still showing up in high-profile journals. So here it is: projections you should stop using (for most things) 👇 #gis #rstats #dataviz dominicroye.github.io/blog/map-pro...

How do people feel about time series charts on mobile (only), running vertically top to bottom, rather than horizontally left to right? Is this an accepted (by readers) pattern yet? #dataviz 📊
Day 29 — Monochrome Each dot represents a living animal. 9 critically endangered land vertebrates remain—2,370 individuals worldwide. The two highlighted dots are Najin and Fatu, the last Northern white rhinos, both female, signifying functional extinction. #30DayChartChallenge #rstats
Fun #dataviz for the #30DayChartChallenge Day8 Circular 👽🛸 UFO sightings around the world reported to the National UFO Reporting Center between 1926 & 2013 (total >80,000). Reports increased since the 1990s, maybe internet made reporting easier or more happening in space? Data via #TidyTuesday
Another #Dataviz for #30DayChartChallenge – Day7 Multiscale. Not sure a colour wheel counts, but here you go. 🎨🍏 Main colour of the top 25 free lifestyle & business Apple apps visualised by hue and saturation. Most apps appear near the outer edge = almost 100% saturation. Made in Svelte
Catching up #dataviz for #30dayChartChallenge Day5 Experimental. Which flower attracts which pollinator? 🌸🐝🦋 Played around with data from the UK Pollinator Monitoring Scheme. For bees or any pollinator plant some lavender, for butterflies go with buddleja aka butterfly bush. Made in Svelte + D3
Stamen is working on a research project about the existing map design & development tooling landscape: what tools people use, where there are gaps, and how workflows could be improved in the future. If you have 10 minutes, please consider filling out our census here! forms.gle/ZWt2m2Yq3o5C...

Journalists can be victims of abuse and even get killed for their work. Iraq & Syria have the highest number of such deaths, while Mexico experienced journalist killings almost every year since 1995. #Dataviz for #30DayChartChallenge Day6 Data day: Reporters Without Borders rsf.org/en/barometer...
Installations of small-scale renewables like solar panels, heat pumps and battery storage have been rising notably in the UK over the past few years. ☀️ 🌬️Plug-in solar panels will soon be legal in the UK too, so hopefully uptake will keep growing #Dataviz for the #30DayChartChallenge Day4 Slope.
Almost two thirds of London is (potential) greenspace, including 24% of residential gardens that can be an oasis for wildlife. I’m very fortunate to have access to one, about 21% of households don’t. Luckily London also has a ton of public parks! #dataviz for the #30DayChartChallenge Day3 Mosaic
Just 42% of household waste gets recycled in England, a trend that has flatlined since 2010 after a decade of improving recycling rates. In some regions, the rate is even lower. The new recycling rules from 1 Apr might change this. 🤞 #Dataviz for #30DayChartChallenge Day1 - Part to whole
The Tate Gallery owns more than 79,000 artworks. About 3% of them are on display right now in the Tate Britain, Tate Modern and Tate Liverpool. You can explore the full collection in their online catalogue www.tate.org.uk/collection #dataviz for the #30DayChartChallenge Day 2 - Pictogram
Every day is a good day for sharing one of the most useful papers about research data ever written. PLEASE get your people to understand and follow this advice. www.tandfonline.com/doi/full/10....
I think there is not enough appreciation to how good this FT visualization is the original is like this 👇
Give me 20! So many things resonated with Evelina's 20 Learnings from a 10 years+ data storytelling journey. 📊 As the first #dataviz specialist in a think tank, my current top 3 relate to advocating for best practice, being a teacher and compromise. What are yours? www.theplot.media/p/give-me-20
