JointJS官网
依赖：jquery，lodash，backbone 如果使用自动排版，需要添加依赖：dagre，graphlib

代码语言：javascript复制 <!-- 引入依赖 -->
<script src="dagre/dagre.min.js"></script>
<script src="dagre/graphlib.min.js"></script>
<script>
// 进行排版
joint.layout.DirectedGraph.layout(graph, {
rankDir: "BT", // 排版方向可以支持'TB' | 'BT' | 'LR' | 'RL'四种方向，默认为TB自上而下
nodeSep: 100, //节点间隔
edgeSep: 100 // 边间隔
});
