Thanks for pointing this out! The attention to exploration is why I enjoy using Observable so I am glad that this will be paired with the framework features to get us Notebooks 2.0
I really like using Observable. Coming from years of d3 and not having a lot of R or Python to do, Observable feels great and things look beautiful. Lots of examples and it is great to see what others are making. Also love that I can use SQL on data in the notebook. The Plot functions can make quick work of various charts. I am looking forward to the static output future, and to see what they mean by more vanilla js in the app.
Not saying it is better or worse than Jupyter etc. Just that it has been exciting to think I can make viz that would not look out of place in major pubs, etc.
