Question

import { Component, OnInit } from '@angular/core';
import * as echarts from 'echarts';
import 'echarts-gl';
import * as $ from 'jquery';

@Component({
  selector: 'app-echarts-glreal',
  templateUrl: './echarts-glreal.component.html',
  styleUrls: ['./echarts-glreal.component.scss']
})
export class EchartsGLRealComponent implements OnInit {

  ROOT_PATH = 'https://echarts.apache.org/examples';

  constructor() { }

  ngOnInit(): void {
    this.initChart();
  }

  initChart() {

    const ec = echarts as any;

    const echartReal3D = ec.init(document.getElementById('echartReal3D'));

    $.get(this.ROOT_PATH +'data/asset/data/life-expectancy-table.json', function (data) {
      echartReal3D.setOption({
        grid3D: {},
        xAxis3D: {},
        yAxis3D: {},
        zAxis3D: {},
        dataset: {
          source: data
        },
        series: [
          {
            type: 'scatter3D',
            symbolSize: 2.5
          }
        ]
      })
    });

  }
}
