It would be interesting to share such templates with exercises. As an example, i like this one: https://observablehq.com/@mitvis/introduction-to-d3 (see "try to recreate the chart below")

Thanks for this article. It sums up a lot of things I like about Observable and alerts me to some things I've missed. For instance, I had never thought about using a mutable as a debugging strategy.

I am really enjoying your article. My eyes are opening to the potential of Observable in so many ways.

Aiming at implementing a kind of Tidyverse in javascript (and hence Observable), Arquero from Jeff Heer appears to me as a considerable step forward (https://observablehq.com/collection/@uwdata/arquero)

Regarding the painful CORS issue indeed, could Observable provide a proxy solution (similar to https://cors-anywhere.herokuapp.com/)?

@fil thanks for sharing and great perspectives in the community section.
