A cartogram is a map that organizes statistical information. A variable is chosen and is represented through land area and colors to represent a type of data. Above is an example of a cartogram and the variable being represented is the 2008 electoral projected votes. Each candidate is defined with a color and the areas shaded that color portray the majority vote in that area. This map uses land area to portray the projected voting for that area.
