I recently found that the drawing animation in one of my notebooks is noticeably slower and choppier than it ever has been before for me, both on the old and new Observable sites: Random Walk Along a Street Grid (Old) Random Walk Along a Street Grid (New) To create the animation effect, I followed the same logic as this example notebook (which does not appear to be any slower than before) that uses a for loop to step through frames and updates a “stroke-dasharray” attr to lengthen the dash to the corresponding proportion of the overall line length. I know my notebook is more computationally intense than the example but I don’t think think that should account for the difference in smoothness. And as I said earlier, it was smooth in the past (see this Bluesky post of a direct screen capture for example). Maybe there is an easy obvious fix I am missing, and if so would appreciate if anyone could point it out! Thanks 3 posts - 2 participants Read full topic

I’ve got several workspaces and my preferences is to work in Mark McClure’s notebooks | Observable. Every time I navigate to new.observablehq.com, I’m taken to Dynamic Data Visualization 373’s notebooks | Observable, though, I suppose because it’s a Pro space. Is there a way to specify which workspace I’d like my to be my default? 3 posts - 2 participants Read full topic

Visnu and Toph reflect on three eras of building Observable features atop LLMs, from a notebook sidebar (2023) to Canvases (2025) to a new experimental prototype, Observable Chat.

Julio joins Mike to explain Observable’s mission to make computation universally accessible and understandable. They talk about the value of open source and community, the challenge of designing social collaboration platforms, and the promise and risks of AI.

Mike and Toph return for the second episode to talk reactivity and making code easier for humans to understand. They show the quirky syntax of Notebooks 1.0, and how Notebooks 2.0 brings reactivity to standard (vanilla) syntax.

In this inaugural (practice?) episode of the Observable Podcast, Mike and Toph share reflections on building with Next.js and how React has evolved over the years. They are excited by, and a little scared of, the magic of React Server Functions.
