US Presidential Elections
Which states and counties voted for Obama... and who didn't?
Based on data collected by the
Associated Press about the US county-level results, we created a dataset that can
directly be loaded into TreeMap. It contains information about
the number of votes made in each county and the percentages obtained by Obama and Romney.
