This is a Choropleth map of the percent of obesity in each states across the United States.  The different color shadings have a significant value to them.  As you can see using the key on the bottom left of the map that states with the color green shades indicate a lower percent of obese people and the state with the lowest obesity percent is the state of Colorado.  The darkest shade of red shows the states with the highest amount of obesity like the states of Mississippi and Alabama.
