A magnetic pendulum simulation, as I've been slowly polishing and moving some @observablehq.com notebooks from the web editor over to blog posts. Observable Notebook Kit is such a joy to use. rreusser.github.io/notebooks/ch...

I did a short interview with @observablehq.com about keeping visuals simple, clear, and easy to connect with. I also touched on curiosity, emotion, and what I’m still figuring out. Grateful for the conversation. 👇

🚨#datavis Job alert 🚨 Fancy working with us in London as a researcher using @observablehq.com Plot for accessible #datavis? To support people with language disability in the use of data visualization for everyday decision making. www.citystgeorges.ac.uk/about/jobs/a...

Observable Plot has crossed 100,000 weekly downloads (and very close to 5,000⭐️s)! observablehq.observablehq.cloud/oss-analytic...

Observable Notebook Kit & Desktop 1.4 now support TypeScript cells, along with TypeScript for Node.js data loader cells. (Just type stripping, but greatly helps interoperability.)

This week, the Bonus Drop features a practical example of using Python data loaders in Observable Notebooks 2.0. They enhance notebook performance by executing code in advance, facilitating access to diverse data formats. dailydrop.hrbrmstr.dev/2025/09/14/b...

A small but significantly useful victory: I got file association working with Observable Desktop.

Big fan of @observablehq.com and since their preview release of Observable Notebooks 2.0 my team at Fora Health have integrated Notebook Kit into our app. Works really well so far. Quick demo ⬇️ screen.studio/share/TqvyfFbU

Observable Notebook Kit and Desktop 1.3.0 are out, featuring data loader cells. You can now (finally!!) write Python and Node.js in notebooks. 🐍 observablehq.com/notebook-kit...

Observable Notebook Kit and Desktop 1.2.0 add Google BigQuery and Databricks database connectors! observablehq.com/notebook-kit...

Oops, seems I broke sign-in in yesterday’s Observable Desktop 1.1.0, but it should be fixed now in 1.1.1. Was it broken for you? Is it fixed now? Please give it a try and let me know. observablehq.com/notebook-kit...

Observable Notebook Kit and Desktop 1.1 are out. Headline feature: database connectors! 🎉 You can now query DuckDB, SQLite, Postgres, and Snowflake directly from notebooks. And it’s self-hosted. And it saves results automatically for performance and stable analysis. observablehq.com/notebook-kit...

📣 Today we’re announcing big updates in Observable Canvases. Learn about our growing suite of built-in, interactive charts (Sankey diagrams, arc maps, beeswarms + more), new embeds and dashboards for fast sharing, added Postgres and Databricks support, and more:

The Notebooks 2.0 gallery now has a dedicated page! observablehq.com/notebook-kit...

A little demo of reactive SQL in Observable Notebooks 2.0, first using (native) DuckDB to bake data from a remote source, followed by DuckDB-Wasm to create and query reactive views in the client. Should be released this week!

I've been playing with the new Observable Notebooks 2.0 over the past days and I'm amazed. While still a preview I think it's already a serious alternative to R or Jupyter notebooks. Love that it works locally now and that notebooks are just HTML files with vanilla JS observablehq.com/notebook-kit/

Notebooks 2.0 is here! 📓🔮 Previewing today:
Notebook Kit, an open file format for notebooks with open-source tooling for generating static sites; and
Observable Desktop, a macOS desktop application for editing notebooks as local files, with a radical new approach to AI. observablehq.com/notebooks/2/

Want to create your own custom marks in @observablehq.com Plot, but don't want to go full D3? I've created a guide with 6 approaches of varying sophistication for specifying reusable custom marks: observablehq.com/@jwolondon/h...

The implementation of the waffle mark in @observablehq.com’s Plot library is a lot more elegant and clever than I thought it would be: open.substack.com/pub/commithi... #javascript #dataviz

🎺 I always like how modest our release notes and version numbers are. But here’s the quack 🐤🐤🐤. Observable Framework v1.13 — just released! — adds support for 🐤 DuckDB’s extensions 🐤 : SPATIAL, H3, VSS… you name it. observablehq.com/framework/li...

I was ★★ by this very simple and yet powerful interaction pattern that the NYT made on their election polls page; I knew I had to reproduce it. Lots of small details to figure out… now it's available as a reusable options transform for Observable Plot. observablehq.com/@observableh...

I am excited about (and proud of) Observable Framework 1.1. It features Windows support, self-hosted npm: imports, and CommonMark compatibility. And it’s just three weeks since launch! More to come.
