This graph displays a sunburst plot whose inner pie has different radiuses, controlled by values in another column.
The sunburst plot shows population density changes of cities in China. According to the Chinese city classification standards, there are 5 tiers. Each color in the sunburst plot represents one tier. Slices with lighter color are population density values for 2010 and the darker ones are for 2016.
