Bubble chart (new editor)

A bubble chart displays one dimension (partition) and two measures. The two measures are plotted on the X and Y axis. The dimension is represented by different colors of the individual bubble areas. Optionally, a third measure can be incorporated; its values determine the radii of the bubble areas.
