Sunburst Chart

This node displays hierarchical data in a radial layout. The view can be accessed either via the “Open view” action on the executed node or on KNIME Hub.
In the node configuration, you can choose input data you want to display and enable certain controls, which are then available in the view. This includes the ability to choose different columns or the possibility to set a title.
The configuration also offers a preview of the view, which should help to get the sunburst chart in the desired shape quickly.
