Classed choropleth maps involved two types of information within the legend; both of range of colors and a range of numbers of what is being measured. In the map above, it measures Beef Cattle Emission in North Carolina in 1992. The legend includes a range of different shades of red which represent a range of emissions; the darker the shade of red, the more emissions released.
