Pie Chart
A pie chart will draw categories and values in a circular disc layout. The pie chart will require you to choose the following selections:
- 
Category: a text field. These will be the labels on the pie slices. 
- 
Value: a numeric field. This will be the size of the slices. 
The pie chart can be additionally be customized to become a donut chart, show categories as a legend, and to show the percentage of the total value of the pie. See Advanced Settings for more information.
