I found these two maps while search for other types of electoral maps and found it quite interesting how the designer decided to portray the political power of Fairfax County.

The regular map of Virginia displays the territorial boundaries of the 40 cities and 95 counties that make up the Commonwealth of Virginia. Each of these cities and counties has been expanded or contracted to show the real proportion of the statewide electorate in the political map of Virginia. Thus, the giant county of Fairfax, Virginia's largest jurisdiction with a population of nearly one million people, is the most prominent feature.

The big political losers are of course Virginia's rural areas, which take up far less space on the political map of Virginia than they do on the territorial map.
