Surfacing this @quarto.org discussion re: “Observable JavaScript” (our old nonstandard syntax). We now recommend and default to standard vanilla syntax, but very much continue to support OJS! github.com/orgs/quarto-...

What do you learn from coding an explanation by hand vs. with Claude? @rreusser.bsky.social has done a lot both ways; on the latest episode of our podcast, we compare one of each. Watch: www.youtube.com/watch?v=7epn... Subscribe: observablehq.com/podcast

Recent improvements: automatic thumbnails for 2.0 notebooks (and fix thumbnails on Bluesky); add collections and edit their metadata (but not yet their contents); speed up navigating your workspace; see recent comments across all your notebooks in one place. observablehq.com/@observableh...
Notebooks now come with a default @duckdb.org database so you can immediately start querying your file attachments or load something with read_csv.
You can now follow users to see their latest notebooks in the “Following” feed on your homepage. You’ll also get an email when they publish something. And we’ve consolidated the personal and community navigation so you see everything on that left sidebar. observablehq.com/@observableh...

Hi Fernando, I explained and documented the Voronoi subdivision in this @observablehq.com notebook back in 2022, well before AI could implement it better than I could myself. observablehq.com/@karimdouieb...
Great post; changes how I look at penguins, their measurement, and Simpson’s paradox itself. @fil.rezo.net reproduced it in a notebook with JavaScript and Plot. observablehq.com/@fil/penguin...
#dataviz #stats #rstats New blog post: Thinking about Penguin Variables Bill length & depth show Simpson's paradox. Re-expressed as size (L×D) and shape (L/D), it vanishes: same data, rotated 45°, a simpler story. friendly.github.io/blog/posts/2...

On the occasion of @arrow.apache.org adopting an official logo (see github.com/apache/arrow...), we’ll note that it, and @columnar.tech’s dbc, have been very helpful in rebuilding the notebook data connectors. Better development experience for us, more performant for you. Thank you! 🙏
Thanks again to James for his bookmarklet! Grateful to have been able to point people to it over the last few weeks. Grateful for people finding crafty ways around our gaps. 🫡
Now @observablehq.com have implemented the export feature natively, so there's no need for my little stop-gap solution any more.
After notebooks 1.0 (2018–), we got inspired by @stephango.com’s 2023 stephango.com/file-over-app, leading to Framework (2023) and then Notebook Kit (2025), upon which we rewrote the site. Still stitching it together: you can now download your notebooks and open them in the desktop app.
If you “Export JavaScript”, you can e.g. publish that module to npm and import it back to a notebook: import {hello} from "npm:example-observable-module" with {type: "observable"}; See observablehq.com/@observableh...

Now looking at relationships between London's school locations and pedestrian traffic collisions. We're going to be making this into a fully explorable dashboard soon, looking at where kids actually commute from, but for now this initial data exploration with @observablehq.com is so useful!
Forgot to link the notebook. Quite an elegant implementation! This is it! (Here at Observable, we still believe in looking at code…) observablehq.com/@tmcw/red-sp...

I've got to say, Observable's AI assistant is a huge win for intitial exploratory data analysis / visualisation! If you know what you're looking for, it puts the wrangling and plot code together really well!! This was done in roughly 5 hours? (Note: data is experimental, for initial exploration)

Some more experiments with @ignfrance.bsky.social PBF vector tiles in @observablehq.com observablehq.com/@neocarto/ve...
Talking about getting more engaged with irl visualization event scene… talking about maintaining a calendar of events or something. Would that be helpful? Seems like @datavizsociety.bsky.social already has that well-covered: datavisualizationsociety.org/events/
October newsletter is going out. We wrote it Thursday, but customer.io optimizer suggested sending it at the start of the next week, so we said fine. But then Toph forgot to check it. So it was sent already stale; database/secrets management has shipped!

Using Vector Tiles with MapLibre in @observablehq.com observablehq.com/@neocarto/ve...
You can now configure databases observablehq.com/team/select?... and secrets observablehq.com/team/select?... within the new Observable. Paste a database URI in the “Host” field and it will populate all fields at once. Release notes: observablehq.com/@observableh...
You can also now attach databases to your chats so the agent can help you explore them. In this example, @rfamdb.bsky.social is an open-access database of RNA families: docs.rfam.org/en/latest/da...

We have some new interactive climate data visualizations through @observablehq.com at observablehq.com/@climatecent.... Hope they are useful, and feel free to share!
Great investigation of a classic dataset. Observable bundles the similar (but later) “cars” dataset from the 1983 ASA Data Exposition, hosted here lib.stat.cmu.edu/datasets/ and described in lib.stat.cmu.edu/datasets/car....

You can now create and manage teams in the new Observable, use Opus 5.5, connect to MySQL… but, most exciting, and by far the most overdue: you can now access SQL cells’ metadata fields by opening the cell menu with ⌃M. Keep those hands on that keyboard! observablehq.com/@observableh...
This has been an issue since we introduced SQL cells in 2021, & was exacerbated by later “UI cells”. Pressing tab inside the cell editor inserts spaces; pressing ⌥tab focuses the next cell. Somehow we never developed any keybinding for focusing controls outside the cell editor, “in-between” editors.
