A nice shift in perceived colour between central and peripheral vision. The fixated disc looks purple while the others look blue. The effect presumably comes from the absence of S-cones in the fovea. From Hinnerk Schulz-Hildebrandt: arxiv.org/pdf/2509.115...

Happy September Equinox! Today the dividing line between day and night runs exactly from the North pole to the South pole, and the sun is directly over the equator. This is an actual image of the Earth today, taken from the Himawari-8 satellite.

Fresh Planet Labs imagery (15Sep v 1Sep) shows already displaced Gazans leaving for the south. Most tents gone - as expected - first from north (Naser) and south (Tel El Hawa) n'hoods.

I naively thought: let's roughly extrapolate the height at which Mondo Duplantis's pole vault world record series would end. The second derivative turns out to be positive! 😱 #math in the wild #tokyo2025 #worldathletics

This year, the ozone hole presented an early development, reaching a larger-than-average area mid-September. On #WorldOzoneDay, #CopernicusAtmosphere continues to provide tools for everyone to monitor the health of our planet.

Gazans displaced from the city due Israeli op have set up tents in Deir al Balah, and near Khan Yunis' Hamad Town. Almost none have yet made it to the south near Rafah, where Israel is setting up two new GHF centers Planet Labs 14Sep/05Sep

I am beyond excited to announce that ggplot2 4.0.0 has just landed on CRAN. It's not every day we have a new major #ggplot2 release but it is a fitting 18 year birthday present for the package. Get an overview of the release in this blog post and be on the lookout for more in-depth posts #rstats

Launch day 🚀 We’ve just released @chartlecc.bsky.social - a daily chart game! Your job is to guess which country is represented by the red line in today's chart. You get 5 tries, no other clues! Play today, come back tomorrow for a different chart with new data and share with your chart friends 📈

Kept drawing, but gave up on the silhouette www.ocearch.org/tracker/deta...

Interesting workflow includes GQIS, Mapshaper, & Illustrator. Data from OSM & analysis of Sentinel-2 imagery. Cameo from hi-res Planet Labs data.

Aaaand they’ve just covered it up. Which is just another layer of irony… …given that this is state action against protest about state action against protest.

All maps are subjective. Some are also Sunderland. www.theguardian.com/uk-news/2025...

Coder tests his productivity with and without AI, collects data and makes charts to argue AI assisted coding is a hype. Great data journalism

✨ I just published a brand-new post! It’s about the notorious SVG <path> element. With its compact Regex-style syntax, <path> can be super intimidating. But they’re also *incredibly* powerful, letting us draw (and animate!) curved lines. You can read it here, and I’ll share more info in thread. 🧵

Weight is an interesting metric for fragility. The Florida grasshopper sparrow, the most endangered bird in the USA, has a total population of about 200 individuals. Adults weight about 17 grams, so there are 3.4 kilos of birds. 7.5 pounds. The weight of a newborn baby.

Yes. This map showing how children’s right to roam free has been removed over four generations always makes me sad.

This outrageously orange Mastigostyla macbridei — spotted at 3000m elevation — represents just the third record of the species in 95 years! 📷 paul-gonzales on iNaturalist 📍 Peru 🔗: www.inaturalist.org/observations... #ObservationOfTheDay

I made this video of fog flowing through the Golden Gate from sunrise to sunset, July 27, 2025, to show why #sanfrancisco is so chilly in the summer. Warm air rising over the Central Valley sucks cold marine air from the ocean into the SF bay. #dataviz #cartography #weather

This is amazing

A massive crowd of Palestinians surrounding aid trucks is visible in July 26 SkySat imagery from @planet.com near the so-called Morag Corridor at 31.3104, 34.2822 in southern Gaza. July 26 video from Ibrahim Alsallout on Instagram showed the crowd from the ground: www.instagram.com/p/DMkmVvNo6n...

I sincerely hope that images like this will some day be used to bring justice. Right now, everyone should see that this should have stopped a long time ago

One of the most powerful tools in my toolbox is SVG. When combined with CSS and JavaScript, we can do some truly remarkable things. ✨ 📝 I’ve just published a brand-new blog post that covers the most critical fundamentals. It’s chock full of interactive demos. 😄 Check it out:

U.S.-funded contraceptives worth nearly $10 million are being sent to France from Belgium to be incinerated, after Washington rejected offers from the U.N. and family planning organisations to buy or ship the supplies to poor nations, two sources told Reuters. www.reuters.com/legal/litiga...

Speaking of labyrinthine contortions, though, here's a little thread of some of my favourite viz over the years.

Are you a journalist writing about a current heatwave? The images you choose are critical to the story. The @climateoutreach.bsky.social team have shown some ideas here which help stress the risks rather than the typical ice creams: www.climatevisuals.org/how-do-you-p...

🗺️ I've spent a lot of time the past week looking at data in the Strait of Hormuz so here is a quick animation showcasing the sheer volume of activity in the Persian Gulf last Friday. The data highlights "Tanker" only vessels (AIS code 80-89) so everything from Crude Oil Tankers to LNG Tankers.

We’re thrilled to unveil the winners of the 2024 #IIBAwards! These works stand out not just for their mastery of #dataviz and storytelling, but for their impact and innovation. See the winners: www.informationisbeautifulawards.com/news/680-ann...

Extensive destruction between April 29 and June 10 in southern Gaza's Tal as-Sultan and Saudi Housing Project visible in imagery from @planet.com. At this rate, there won't be anything left of either neighborhood in the next month or two and it's not clear where the displaced will be able to live..

Happy 18th birthday ggplot2! #rstats

A female Western Gull was recorded riding 150km in a garbage truck from San Francisco to a compost facility in Central CA, probably to forage. TWICE. An innovator, an icon, a genius. This is one of my favorite @waterbirdsociety.bsky.social papers I've ever handled as managing editor #ornithology

Potentially interesting for journalist among my followers: I contribute to this training school in Rome in September: "From Space Journalism to Satellite Journalism: The Big Picture" www.espi.or.at/espi-luiss-d...

“The FT found that more than four-fifths of Gaza — which was among the world’s most densely populated territories even before the war triggered by Hamas’s October 7 2023 attack — is now covered by Israeli military zones and evacuation orders.” on.ft.com/3Hof4pF

Fascinating read about the discovery of infrared, and how space telescopes are like sensory implants "becoming part of how we know"
