Above is a map of 2018 GA governor race with the familiar red/blue treatment, coloring all units (in this case counties) with a solid color regardless of the size of the electorate within. Accordingly, sparsely-populated counties in Trumpland dominate the color balance. Such maps are known as choropleth maps.
But as the saying goes, “land doesn’t vote.” Another way of displaying the results is by a dot map, with the density of dots, red or blue, indicating where the votes are. In this technique, each dot represents a fixed number of votes, say 1,000. If a county has, for example, 10,000 votes, then 10 dots are randomly placed within the county polygon. Here’s what it looks like for the Abrams race:
2018 GA Gov dot map, blue = 1,000 Abrams votes, red = 1,000 Kemp votes
So that’s quite a different picture. A closer view of the Atlanta area:
