Pie charts are round representations of your data, cut into slices. Each slice represents a piece of data, and the size of the slice is proportionate to the data that it represents. Double-clicking on a slice lets you drill down into your data.
Pie charts are a great way to show numerical or financial data, in other words, what
something is worth relative to the whole group. 
Sunburst visualizations organize and display your data in a series of colorful rings. Starting with the center ring, each ring going outward represents more detailed information relating to the inner ring to which it is connected. These outer rings are arranged and colored to indicate their hierarchical relationship with the inner ring. Any fields that contain empty slices can be shown as gaps in the sunburst.
You can drill-down into your data by double-clicking on a data slice. The sunburst then rearranges itself to show the more detailed information.
Sunburst visualizations are particularly well-suited for numerical analysis of hierarchical
data.
