If you'd like to skip the story and just play with all the graphics and #dataviz, that's okay too! Here's a link directly to the explorer diagramchasing.fun/2026/portrai...

I've been persuaded by @infowetrust.com's recent arguments about using "chartmaking", instead of more technical terms such as "information design" or "data visualization", to refer to what we do

My Infantino caption hands obsession is paying off! From a student comic…

Big box of 1920s data graphics just arrived from Japan. First copies of many this side of the world?

"With the rocket set up, all that remained to do was ignite it. Goddard’s assistant, Henry Sachs, did this by using a blowtorch attached to a long stick...There was no formal countdown." [email protected] on Robert Goddard's historic rocket launch #OnThisDay in 1926 (HT @nytimes.com) 🚀

Spending the next week as the cartoonist-in-residence at The Map Center in Pawtucket, RI! Wanna come see me inking pages in person AND get your ear talked off about cartography by @mapcenter.com? It’s pretty magical in here.

Every field needs someone who keeps it from forgetting itself. @datavisfriendly.bsky.social has spent decades doing just that: giving data graphics a memory. My latest for CHARTOGRAPHY: www.chartography.net/p/data-graph...

Great insight about marriages in Spain by @pablogguz_! In 1976 over 99% of first marriages in Spain were Catholic. By 2024 the number of marriages has halved and about three in four marriages are now Civil. The country turned its back to religion and the institution of marriage.

YES! After a few hours searching, I finally dug up a high-quality scan of the first (known) color choropleth. From haab-digital.klassik-stiftung.de/viewer/fulls... Thanks to @datavisfriendly.bsky.social & @infowetrust.com who helped with the search. #cartography #maps #dataviz

One brillant idea here is to combine the inputs and outputs in the middle instead of trying to connect precisely the sources and destinations, creating an unreadable spaghetti.

I somehow missed this acquisition. The original flowmap. Likely directly inspired Minard during his tour of British rail systems. Look at those rich textures! Henry Drury Harness, IRISH RAILWAY COMMISSION, 1838 www.davidrumsey.com/luna/servlet...

Last night I shared my obsession for beautiful data graphics at @abaararebooks.bsky.social SF Book Fair. One of the sharpest audiences I've ever presented to.

RJ acquires another historic chart.

Thank you for writing this book, RJ! I appreciate your attention to detail; it made me smile more than once. :)

It’s nice to see different plotted alongside the original and updated data. It’s extremely difficult to discern the distance between two curves (we tend to perceive the maximum distance, not the vertical distance).

About to go live chatting inequality with @jeremybney.bsky.social open.substack.com/live-stream/...

The graphic comparison at the heart of inequality—us versus them, rich and poor, haves and have-nots—feels older than money itself. The forms will keep changing. The comparison will not. Read my latest for Chartography: www.chartography.net/p/the-geomet...

I'm a sucker for a pretty style guide. mtc.ca.gov/sites/defaul...

A truly original way of visualizing population data. Population median lines for European countries show where the population is cut in half along a North-South axis. Love the use of one continuous line. Great piece!!! Source: buff.ly/U5W7TUm
