    </div>
</template>
<script>
import Vue from 'vue';
import { TreeMapPlugin } from "@syncfusion/ej2-vue-treemap";
Vue.use(TreeMapPlugin);

export default {
  data: function() {
    return {
    height:'350px',
     dataSource: [
        {State:"United States", GDP:17946, percentage:11.08, Rank:1},
    {State:"China", GDP:10866, percentage: 28.42, Rank:2},

            labelStyle: {
                color: '#000000'
