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.

Example

<div id="treemap"></div>
<script>
  $("#treemap").kendoTreeMap({
      dataSource: [
          {
              name: "Technology",
              value: 30,
              items: [
                  { name: "Mobile", value: 15 },
                  { name: "Desktop", value: 15 }
              ]
          },
         
      ],
      valueField: "value",
      textField: "name"
  });
</script>
