ZCubes/Donut With Labels
Donut charts display data in rings, where each ring represents a data series. If percentages are displayed in data labels, each ring will total 100%. Donut charts provide a better data intensity ratio to standard pie charts since the blank center can be used to display additional, related data.
ZCubes facilitates the user to include labels in the Donut Graphs which make it simple to understand and gives other editing options also.
