st: Density/Geographical Maps

[Fredrik Wallenberg <fredrik@sims.berkeley.edu>]

There is a package for "R" that allows you to work with geographical 
maps (at least US state/county maps). I haven't looked into it in 
detail but at the very least you can select the shade of each object 
based on a value so it works great for depicting densities across 
geographical areas. There is a similar plug-in for Excel if you are on 
Windows (which I'm not). Does nayone know of anything like that for 
Stata?
