您正在寻找的功能内置于GoJS。例如，请查看

组织结构图编辑器示例。

The functionality you're looking for is built in to GoJS. For instance have a look at the
Org Chart Editor Sample.

您可以双击节点以添加新人，将节点拖到另一个节点上以更改关系，并绘制链接（通过单击拖动操作）从节点的背景到没有boss的其他节点。

You can double click on nodes in order to add a new person, drag a node onto another in order to change relationships, and draw links (with a click drag operation) from a node's background to other nodes that have no "boss".

（如果你希望节点在这个简单的示例中没有Boss，你可以选择和删除链接）

(If you want a node to have no Boss in this simple sample, you can select and delete links)
