This attribute provides text label with some default description for the following elements in the TreeMap.

Element	Default description

Change this default description using the Description property available in the TreeMapLegendSettings, TreeMapTitleSettings, TreeMapSubTitleSettings, and SfTreeMap. It helps screen readers to read for assistive purpose.
