Just to jump in and say my comment that you said wasn't true was "... improvement over an existing literate programming environment.".

I don't argue that you might find a different notebook environment more suitable. That's totally up to taste, preferences, and silly do argue about.

But observable (the reactive notebook technology) can do everything a jupyter notebook can do, you just need to write a bit of communication code to hook up a websocket. (For me sandboxing the ui is a feature not a bug.)

And you can also self host it on a machine of your choice, and edit it locally.

We do that internally for all our dashboards.
