2012 Presidential Elections Popular Vote
The following chart is a good example of displaying diverging data using color. We set “50%” as the neutral point and show higher values in one color and lower values in another color. We show “50%” as white and the color gets darker as values diverge from 50%. The value being measured in this chart is the percentage of votes for Barak Obama. You can use the mouse to hover over a state (or, on a touch device, use your finger to touch) to see additional details.
