Bubble

This demo illustrates use of the bubble series type. This series can be used when you need to visualize a data set with three dimensions: the first two dimensions are indicated by coordinates on the axes, the third by the size of the bubble. In this demo, the bubble size helps estimate the percentage of people with age over 60 to the total population in the country.
