Where can I find a freeware or shareware download for Mac OS X that will allow me to plug in numerical data (e.g., public library funding in a given year) for each U.S. State and get a map of the USA that displays color-coded states? Like the infamous red / blue states map, which also has county breakdowns.

I've tried EuroOffice's Map Chart extension with OpenOffice for Mac and ran into the Python-related bug they warn about; EuroOffice does not come in Mac OS X. Most of the other apps I can find either come in Windows only (such as Microsoft MapPoint), are hideously expensive, or both. I am not looking for 3-D visualization or GIS, just for a way to create a 2-D map that represents numerical data by U.S. state (and county would be nice as well).
I currently am using Mac OS X 10.4.11.
I am willing to pay up to $50 but $25 or less would be preferable.

You can do it in R if you're willing to learn a little programming:

map("county", regions=c("washington,king", "texas,travis"), fill = TRUE, col = "blue", add = TRUE)

Results look like this

Google charts API has state breakdown, but not county.

Here - Zmaps Color your map, via Mefi's own Mcwetboy's blog. Search for choropleth on his blog and there are likely other links.

Also, I couldn't get this to work, but I'm on shitty IE6. Maybe it will work for you. Geocommons Map Maker (free registration req'd).

Also, the choropleth tag on delicious will probably be helpful to find other apps/software.

Response by poster: Thank you very much for these links. I know a bit of HTML so I'll see what I can do with the Google Charts, though what I'm planning isn't a webpage but a still for a PowerPoint.
