Does this notebook have unpublished changes? I don’t see any references to d3.group here, just d3.nest.

Interesting... I was trying to keep the original notebook, and merging @fil changes in a Fork, so I did this:

1. Merged @fil changes into the original one (the one with nest)
2. Fork it, and rename the fork "group". This this document and then had the changes
3. Revert the original to my old version

Seems like by doing that the fork also reverted. Is that how it is supposed to be?

Seems like I fixed it. Thanks for noticing Mike, I still get very lost with Observable's comparing/merging system. It is hard for me to know which one is getting the changes when I hit the merge button.

My current theory is that I didn't published the changes in the fork (here), and maybe because of that reverting the parent changed this one...

Also, is kind of sad that only I appear as an author on the notebook, despite it having so much of @fil's code

Need to be logged in for this data source 😞

Thanks a lot, they changed the policy.... Replaced it with a cached file

thank you!  this notebook is super useful, which is why I mentioned it.  😀
