This chart displayes hierarchical data in a radial layout:
The circle in the chart center represents the hierarchy's root node.
Sections further outside represent nodes that are located deeper in the hierarchy.
Each leaf node has a attached value attribute. For sections corresponding to leaf nodes, the area is derived from the leaf node's value attribute. For sections not corresponding to leaf nodes, the area is derived from the accumulated value of all descending leaf nodes.
This node expects a data structure that satisfies certain requirements:
The following table gives an example for such a data structure:
