I've learned a new word today...

Wow, I'm the statistician and I didn't even know they were called choropleths, lol!

Then the day hasn't been a total waste... :-)

IIRC, I picked up the term from Edward R. Tufte's superb little book, The Visual Display of Quantitative Information.

Thanks. I've browsed through that book before. Lots of good things in there. It's highly recommended by everyone I know. I should sit down and read it! He's got another one out I've been meaning to read that also got rave reviews called Envisioning Information.

I've been threatening to get that book for years decades!
