Color mapping is used to customize the color for each group or item based on the specified types. The following options are available to customize the group and leaf items in the TreeMap.
Range color mapping is used to apply color to the items by giving specific ranges in the DataSource, and it should be specifying the data source properties to the rangeColorValuePath. The color mapping ranges to be specified in the from and to properties of the colorMapping.
