星球案例

vue中使用vis.js

安装

style 中有使用 less，所以需要安装一下；

   npm install vis --save

   npm install less less-loader --save 

在需要使用的组件内引入vis

   import vis from 'vis'

定义dom

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

容器渲染

  <script>
     import vis from "vis";
     export default {
             data() {
                 return {
                    nodes : [
