d3.js实现股权穿透图(vue+d3.js)

业务需求

前段时间写过一篇使用relation-graph插件实现的股权穿透图效果(relation-graph实现股权穿透图),但是目前公司有了新需求,想要连接线上携带股权百分比。之前的插件兼容性有点小问题,所以只能换个思路去实现(d3.js+vue)。

1、实现的效果图

在这里插入图片描述

2、安装依赖

npm install d3 --save-dev

3、全部代码(复制粘贴即可实现)

<template>
  <div id="appc" style="height: 650px"></div>
</template>
<script>

留言:
1:点击展开节点按钮再加载子节点数据还在尝试中。所以只能是让后端一次性返回所有数据。
2:数据只能单侧延伸。解决思路:还在尝试跟之前relation-graph实现股权穿透图文章一样点击节点后,弹窗作为根节点展示此节点的穿透图。
3:欢迎大家有更好的实现方案沟通交流。
