When I encounter an unknown in Observable, I try to create a simple tutorial notebook to help myself ( and perhaps others ) learn how to do it, so I can go back to it for reference. Here’s one I created a few days ago on importing Data Sets.
Thanks for this. One of the things I really like about the computational notebook paradigm adopted by Observable is that it supports people not only solving problems, but providing narratives to explain how they were solved. Compared to other some notebook environments, the barrier to entry in doing this is low with Observable and for those reading adapting those narratives, is even lower.
