IDL is not distributed with the county data base you are seeking. You will have to load the data, and maybe write some code to plot it. You may find that sort of data at a number places. I've seen (but not used) something like it from the US census at URL: http://www.census.gov/geo/gis/gis-fag.html , or http:/tiger.census.gov/ good luck.
