Most radars on the workbench are created using reports.   

For example, the My Matters Radar consists of 3 reports:

• My Cases
  The My active case count report, which is a card chart type.
• Breakdown by type
  The My active case work type breakdown report, which is a donut chart type.  It is also interactive with the Breakdown by phase report and the My Matters list view.
• Breakdown by phase
  The My active case phase breakdown report, which is a bar chart type.  This is dependent on the Breakdown by type report.

These radars are configured using the Report View widget.
