-> 一个简单&强大的Web思维导图库
+> 一个简单&强大的Web思维导图

-Demo：[https://wanglin2.github.io/mind-map/](https://wanglin2.github.io/mind-map/)
+本项目包含两部分：

-文档：[https://wanglin2.github.io/mind-map/#/doc/zh/](https://wanglin2.github.io/mind-map/#/doc/zh/)
+1.一个js思维导图库，不依赖任何框架，你可以使用它来快速完成Web思维导图产品的开发。
+
+开发文档：[https://wanglin2.github.io/mind-map/#/doc/zh/](https://wanglin2.github.io/mind-map/#/doc/zh/)
+
+2.一个Web思维导图，基于思维导图库、Vue2.x、ElementUI开发，可以操作电脑本地文件，所以你可以直接把它当做一个在线版思维导图应用使用，如果觉得github的响应速度慢，你也可以部署到你的服务器上。
