dataSource Object|Array|kendo.data.HierarchicalDataSource

The data source of the treeMap which is used to display the tiles and titles. Can be a JavaScript object which represents a valid data source configuration, a JavaScript array or an existing kendo.data.HierarchicalDataSource instance.

If the HierarchicalDataSource option is set to a JavaScript object or array the widget will initialize a new kendo.data.HierarchicalDataSource instance using that value as data source configuration.

If the HierarchicalDataSource option is an existing kendo.data.HierarchicalDataSource instance the widget will use that instance and will not initialize a new one.
