The following code sample demonstrates the output.

<template>
  <div id="app">
    <ejs-button @click="addChart">Add Chart</ejs-button>
  </div>
</template>

<script setup>
import { provide } from "vue";
import { ButtonComponent as EjsButton } from '@syncfusion/ej2-vue-buttons';
import { Chart } from "@syncfusion/ej2-charts";
import { LineSeries } from "@syncfusion/ej2-vue-charts";
Chart.Inject(LineSeries);

var count = 1;

provide('chart', [LineSeries]);

const addChart = () => {
  var chartEle = document.createElement('div');
  chartEle.id = 'container' + count;
  document.getElementsByTagName('body')[0].appendChild(chartEle);

  let chart = new Chart({
    series: [{
      type: 'Line', xName: 'x', width: 2, marker: { visible: true },
      yName: 'y', name: 'Germany',
      dataSource: [{ x: 1, y: 21 }, { x: 2, y: 24 }, { x: 3, y: 36 },
      { x: 4, y: 38 }, { x: 5, y: 54 }, { x: 6, y: 57 }, { x: 7, y: 70 }],
    }],
    title: 'Inflation - Consumer Price', tooltip: { enable: true }, height: '400', width: '800'
  });
  chart.appendTo('#' + chartEle.id);
  count++;
};

</script>

<script>
import { ButtonComponent } from '@syncfusion/ej2-vue-buttons';
import { Chart } from "@syncfusion/ej2-charts";
import { LineSeries} from "@syncfusion/ej2-vue-charts";
Chart.Inject(LineSeries);

var count = 1;
export default {

components: {
"ejs-button":ButtonComponent
},
  data () {
  },
  provide: {
    chart: [LineSeries]
  },

      var chartEle = document.createElement('div');
      chartEle.id = 'container' + count;
      document.getElementsByTagName('body')[0].appendChild(chartEle);

      let chart = new Chart({
          series: [{
              type: 'Line', xName: 'x', width: 2, marker: { visible: true },
              yName: 'y', name: 'Germany',
              dataSource: [{ x: 1, y: 21 },{ x: 2, y: 24 },{ x: 3, y: 36 },
                      { x: 4, y: 38 },{ x: 5, y: 54 },{ x: 6, y: 57 },{ x: 7, y: 70 }],
              }],
          title: 'Inflation - Consumer Price', tooltip: { enable: true }, height:'400', width: '800'
      });
