Sunburst widget

Sunburst chart — also known as ring chart, multi-level pie chart, or radial tree map — is typically used to visualize hierarchical data structures. It consists of an inner circle surrounded by rings of deeper hierarchy levels. The angle of each segment is either proportional to a value or divided equally under its parent node.

Sunburst can be used to visualize energy consumption per type, per equipment, per building floor or run hours of all chillers in the building and compressors in each chiller. It is dynamic and interactive, so user can quickly compare real-time or historical values.
