Range Graded Proportional Circle Map

Range graded proportional circle map
A range graded proportional circle map uses circles to group the data into circles, keeping in mind their relative sizes that depicts the data being displayed. Circles are used because they are easy to scale and measured using the radius. This example shows the population of Europe by country, by using relatively different circle sizes in the map, you can easily distinguished the different populations.
