vue create quickstart
cd quickstart
npm run serve

Initiating a new project prompts us to choose the type of project to be used for the current application. Select the option Default ([Vue 2] babel, eslint) from the menu.

Add Syncfusion TreeMap package

All Syncfusion Vue packages are published in npmjs.com registry. To install Vue TreeMap package, use the following command.

Register TreeMap Component

You can register the TreeMap component in your application by using the Vue.use(). Refer to the code example given below.

import { TreeMapPlugin } from '@syncfusion/ej2-vue-treemap';

Vue.use(TreeMapPlugin);

Registering TreeMapPlugin in Vue, will register the TreeMap component along with its required child directives globally.

Add the Vue TreeMap by using ejs-treemap selector in template section of the App.vue file.

<template>
    <div id="app">
        <ejs-treemap :dataSource='data' weightValuePath='Count'
     :leafItemSettings='leafItemSettings'></ejs-treemap>
    </div>
</template>
<script>
    import Vue from 'vue';
    import { TreeMapPlugin } from '@syncfusion/ej2-vue-treemap';

    Vue.use(TreeMapPlugin);
    export default Vue.extend ({
	    data: function() {
		    return {
			    dataSource: [
					{ State: 'Brazil', Count: 25 },
					{ State: 'Colombia', Count: 12 },
