vue JointJS 实例demo

前言

　　越来越发现，前端深入好难哦！虐成渣渣了。

　　需求：前端绘制灵活的关系图(此demo还是简单的，我的需求才跨出一小步)

安装

　　npm install jointjs

容器，工具栏

    <div id="toolbar">
                <button class="btn add-question" :click='addNode'>Add Node</button>

                <button class="btn preview-dialog">Preview Dialog</button>
                <button class="btn code-snippet">Code Snippet</button>
