Range Graded Proportional Circle Maps are another type of Proportional Circle map, which conveys its point data with circles. What distinguishes this map from others is that it's range graded, meaning only a set number of circles are designated to be used in the map. The above map is a range graded proportional circle map that conveys the unemployment percentages in 2000 in the United States. It is range graded because there is a set number, 5, of circles used, specified in the legend on the right, with each circle representing a interval of percentages for that circle's size.
