Data Binding

The tree map control supports data binding using the dataSource property.

Populate data

The [dataSource] property accepts collection values as input. For example, a list of objects can be provided as input. Data can be given as either flat or hierarchical collection to the [dataSource] property.

Flat collection

The following code shows how to bind a flat collection as data source to the tree map control.

    <div class="control_wrapper">
        <ejs-treemap id="treemap"  :dataSource='dataSource' :weightValuePath='weightValuePath' :leafItemSettings='leafItemSettings'></ejs-treemap>
import Vue from 'vue';
import { TreeMapPlugin } from "@syncfusion/ej2-vue-treemap";

export default {
  data: function() {
    return {
     dataSource: [
