Via Twitter I saw 275,000 Groups Lose Charity Status After Failing to File Paperwork With IRS from the Chronicle of Philanthropy and thought it might make for an interesting choropleth map. I’ve been wanting to set up a very basic workflow for generating simple choropleths in protovis, so this seemed like a good data set and a good opportunity. It took about an hour, but next time it shouldn’t take but a few minutes (in theory).
*Update*
I’ve updated the map now that CO, CT, DE, and NE are included in the data dump from The Chronicle of Philanthropy. Thanks, Lisa!
