This is an example of a classed choropleth map of breast cancer rates of white women in the United States.  In the image above is broken down into five classes determined by different colors and each color has its own statistical value.  The light yellow color represents the lowest level of cancer rates which ranges from 15.88-21.56 percent.  The majority of the southern states appear this color.  The highest cancer rates are the dark red colored states and that seems that cancer rates are highest in the New England region.
