描述：

GoJS是一个用于构建交互式图表和图形的JavaScript和TypeScript库。GoJS允许你为你的用户建立各种各样的图表和图形，从简单的流程图和组织图到高度具体的工业图，SCADA和BPMN图，医学图，如基因图，等等。GoJS使用可定制的模板和布局使构建复杂节点、链接和组的JavaScript关系图变得容易。

1. 安装

参考： https://www.npmjs.com/package/gojs

   npm install gojs --save

2. 引入

import gojs from 'gojs'
Vue.prototype.go = gojs

3. 使用

去除水印

找到go.js文件，在node-modules文件夹中找到gojs夹，然后搜索gojs）

在go.js中搜索 7eba17a4ca3b1a8346，如

因为每个版本打包后的文件不一样，所以找到 7eba17a4ca3b1a8346 语句中的位置，然后把当前语句的替换掉。

a.xr=b.V[Ra(“7eba17a4ca3b1a8346”)][Ra(“78a118b7”)] (b.V,Jk,4,4);

替换成

a.xr=function(){return true;};
