Just a note here: there is survey data showing up in the notebook because its outputs haven't been cleared. We might want to clear the notebook and/or remove/comment out the df.head() calls, then rewrite Git history (I think a git commit --amend --no-edit then git push -f should do it, but there might be other ways too)

Thanks a lot for catching that @michellewang! Just forced pushed to remove the notebook - let me know if things still don't look right.

Looks good to me! Also realized that my screenshots in the other PRs also technically show data (in map colours/hoverboxes/bar plots) -- should I remove those as well or do you think it is less of an issue?

@michellewang I believe that’s fine for now, since that’s likely the desired behaviour for the plots in the app anyways !

Thanks @nikhil153 for your work on this 🎉. I pushed some minor clarity-related changes to the code and simplified the plot formatting a bit so it looks more like the Yale climate map bar plots.

The stacked bars are currently still missing full-text labels for the actual outcomes ("Moderately agree", "Agree", etc...), but because I think we need additional info about which ones to use when the bars are binarized, I've opened a separate issue for that.

Will merge this as is for now!
