This is really neat! 'Been using observable for about a year now, and I really appreciate how easy it is to share notebooks with it. Circular dependencies can be fun, but that's not really unexpected considering the model y'all use.

How well does this framework do with something relatively complex like an animated choropleth? Vega-lite and D3 can do them both, but they can both get complicated pretty quickly.

We (and by we I really mean my inimitable collaborator Philippe Rivière) have started prototyping plugins for rendering geographic shapes using D3 projections, so I expect Plot would be able to support this fairly soon. Then you can use something like this Scrubber component to drive the animation:

Nice, thanks! Scrubber is what I use now, and it's great. Can't wait to see the geometric plugins.
