| SunburstItemCollection |
A SunburstItemCollection object that contains SunburstItem objects.

This example shows how to manually add items to a sunburst.
Assign a SunburstItemStorage object to the SunburstControl.DataAdapter property. The SunburstItemStorage stores manually created items using the SunburstItemStorage.Items property that returns a collection of SunburstItem objects.
Each object can have a child items’ collection that is available using the SunburstItem.Children property.
Use the SunburstItem.Value property to specify an item value.
The SunburstItem.Label property allows you to modify the text the item shows.
