效果图：

• 先在vue项目中安装antv G6

 npm install --save @antv/g6

• 安装完之后引入，我是将整个结构图的某些相关配置进行了封装，写在了公共js文件里面，若是你们不想封装可以直接在你们相关的vue文件里面引入  

import G6 from '@antv/g6';

• 然后封装名称为renderMap的函数，名字可以自定义

export function renderMap(data,graph){
  const COLLAPSE_ICON = function COLLAPSE_ICON(x, y, r) {
    return [
      ['M', x - r, y - r],
      ['a', r, r, 0, 1, 0, r * 2, 0],
      ['a', r, r, 0, 1, 0, -r * 2, 0],
      ['M', x + 2 - r, y - r],
      ['L', x + r - 2, y - r],
    ];
  };
  const EXPAND_ICON = function EXPAND_ICON(x, y, r) {
    return [
      ['M', x - r, y - r],
      ['a', r, r, 0, 1, 0, r * 2, 0],
      ['a', r, r, 0, 1, 0, -r * 2, 0],
      ['M', x + 2 - r, y - r],
      ['L', x + r - 2, y - r],
      ['M', x, y - 2 * r + 2],
      ['L', x, y - 2],
    ];
  };
  G6.Util.traverseTree(data, (d) => {
    d.leftIcon = {
      style: {
        fill: '#3759B0',
        stroke: '#e6fffb',
      },
    };
    return true;
  });

  G6.registerEdge('flow-line', {

  graph.on('node:mouseenter', evt => {

    graph.setItemState(item, 'hover', true)
  })
  
  graph.on('node:mouseleave', evt => {
    const { item } = evt
    graph.setItemState(item, 'hover', false)

}

• 然后需要在相关的vue文件中引入这个封装好的公共函数renderMap

import G6 from "@antv/g6";
import { renderMap } from "../../../assets/common/http";

• 直接呈上完整vue文件，里面有几个需要注意的点，用注释标注了

<template>
  <div>
    <div id="container"></div>
  </div>
</template>

<script>
