I transformed the original CSV with a pivot table (in Apple Numbers) and re-exported to CSV. I used python to dump it to JSON, and find and replace to change TRUE and FALSE to NotDisadvantaged and Disadvantaged, etc.

This is working well, but there could be a couple of improvements (that granted could be captured in future cards)

• Adding a tooltip to each state with their disadvantaged percentage
• Adjusting the quartiles of the coloring to mre interestingly reflect the data. (There are no states above 75% (thankfully)

I took a quick pass at adding the tooltips, but I'm a little wary of wasted motion here since we're about to refactor this all into one map in #105, so I think commenting on that card makes sense 👍.

Thanks for the review!
