如何在GoJS中动态添加节点数据和链接数据？

Question

 myDiagram.model = new go.GraphLinksModel(
[

  { key: "Alpha", color: "lightblue" },
  { key: "Delta", color: "pink" }

],
[
  { from: "Alpha", to: "Alpha" },
  { from: "Delta", to: "Alpha" }
]);

我需要动态添加更多值,我该怎么做？

节点数据(来源:GoJS docs,class Model):

如果要从nodeDataArray添加或删除节点数据,请调用addNodeData或removeNodeData方法.

链接数据(来源:GoJS docs,类GraphLinksModel):

如果要从linkDataArray添加或删除链接数据,请调用addLinkData或removeLinkData方法.如果要修改链接所连接的节点,请调用setFromKeyForLinkData和/或setToKeyForLinkData方法.
