This is a nice exmaple of a macro - this allows you to maintain
a single copy of the code that draws the map, but pass different
parameters in to display the desired counties & colors.
Note that I'm annotating the gradient background, and the 'shadow'
of the map. I'm also annotating the 'title' rather than using a
title statement, so it can share the same x/y space as the map.
You can hover your mouse over the counties, to see the county names.
