需求

项目中的原型图需要使用react实现一个拓扑图（关系图）
通过查找，找到了可以使用的类似的原型：以下图片地址。
通过项目需要以及修改，形成了下边的样式

echarts代码

// 调试页面回打印出点击的节点名称
var size = 50; //节点大小var listdata = []; 
var links = []; 
var legendes = ["手机IMSI", "人脸ID", "车牌号码", "人脸ID"];
var texts = []; var phoneNum = {"手机号:[phone]": "13856978256","手机号:[phone]": "13998745632","手机号:[phone]": "18812345678","手机号:[phone]": "16812345678","手机号:[phone]": "13856978256","手机号:[phone]": "13998745632","手机号:[phone]": "18812345678","手机号:[phone]": "16812345678","手机号:[phone]": "13856978256","手机号:137895632": "13998745632",

myChart.on("click", clickFun);

react代码

在react中使用时遇到了一个异步的问题，通过componentDidUpdate监听了数据的更新变化

import React, { PureComponent } from 'react';
import './index.less';
import * as echarts from 'echarts';
class RelationEcharts extends PureComponent {constructor(props) {super(props);this.chartRef = React.createRef();this.state = {//在这里存放对应数据//数据类型是一个对象，需要做相应的转化展示到页面对应的位置}}componentDidMount() {this.init();  //发送异步请求，并在请求成功后更新状态};componentDidUpdate(prevProps, prevState) {if (prevState.floorName !== this.state.floorName) {this.initChart(); //检查更新操作}}init() {//在这里发送异步请求}initChart() {//在这里引入echarts的配置}render() {return (<div ref={this.chartRef} style={{ width: '100%', height: '80%', paddingLeft: '20%' }}></div>);}
}export default RelationEcharts ;
