最近我司项目中需要加入流程图制作功能，于是乎百度各种找可视化绘制拓扑图的轮子，大部分都是国外的，看文档太吃力，不过好在最终让我发现了AntV G6流程图图表库，最新版为2.0，不过编辑器在2.0版本还没有进行开源，所以只能退而求其次，使用了1.2.8版本。希望2.0版本的编辑器尽早开源，在交互方面1.2.8版本还是差了一些。该组件并
非开箱即食，需要根据自己的业务进行修改，右侧属性表单部分如果有时间考虑改为插槽形式，方便以后复用~
如何将数据进行数据可视化展现？

流图属性
参数 | 说明 | 类型 | 可选值 | 默认值 |
actionList | 动作数据 | Array | —— | [] |
funcList | 功能数据 | Array | —— | [] |
accountList | 账号数据 | Array | —— | [] |
workflowList | 流图数据 | Array | —— | [] |
nodeTypeList | 节点类型数据 | Array | —— | |
所有属性接收的数据格式需要与nodeTypeList的默认值相同流图事件
事件名 | 说明 | 参数 |
saveData | 当用户手动点击保存触发事件 | source,type |
参数type可为空，在此项目中主要用来区分新建与编辑
流图方法
方法名 | 说明 | 参数 |
clearView | 清空当前视图 | —— |
source | 渲染数据 | nodes, edges, name, type |
参数type与事件中相同，参数name的作用是用来取流图名
