THE POWER OF CARTOGRAMS: These two maps both depict the results of the recent senatorial vote in Georgia. They both have the same color scheme for the margin of victory per county –– a continuous blue-red scale.
But the cartogram on the right graphically depicts the demographic proportions involved and thereby explains how Warnock could win while victorious in only 30 out of 159 counties.
The cartogram really illustrates the power of people's votes. I wish the press and news media would use more cartograms, since it is so hard to understand the demographic realities from a conventional map.
