We’ve been rebuilding the editor atop the foundation of Notebook Kit and portable files in an open format. You can’t necessarily tell yet, since there’s no button… but thanks to James for seeing it! See also @nxrix.bsky.social’s remarkable depicted notebook: new.observablehq.com/@nxrix/binar...

Breaking News! Code: y-axis alert. Nino 3.4 SST is now up to 3.63 SD above the 1991-2020 baseline, about 1-in-7000 in the absence of anthropogenic warming. There's not enough room in a single post to express just how crazy this is. Please read: climatecasino.substack.com/p/some-monst...

In our latest podcast, @toph.me & @visnup.bsky.social explore the new community listings & nice touches in our new editor. (You can make a notebook in one click instead of three. Mousing over the left gutter doesn’t flash five buttons. Files work with versioning.) www.youtube.com/watch?v=4uDe...

Revisiting this is a great idea by @thelatentspace.bsky.social, and it sent @toph.me down a rabbit hole: when you fill in all the years in-between, you get a lot of self-intersection. new.observablehq.com/@tophtucker/...

Mike Bostock's first data viz library ran on three 1x1 pixel GIFs and raw HTML tables. It kind of made a bar chart. He went on to build D3. Listen now on Spotify (open.spotify.com/episode/01BJ...) and Apple Podcasts (podcasts.apple.com/us/podcast/t...).

Observable Plot hit >100k daily downloads yesterday for the first time! Literally “off the chart”! (Because we set the maximum of the y domain to the 99.5th percentile in order to occasionally give ourselves this satisfaction.) Congrats to Mike and Fil! observablehq.github.io/oss-analytic...
