GoJS中go.Model和go.GraphLinksModel分别如何使用

Question

demo1中代码 链接描述

myDiagram.model = new go.GraphLinksModel(
    [
      { key: "Alpha", color: "lightblue" },
      { key: "Beta", color: "orange" },
      { key: "Gamma", color: "lightgreen" },
      { key: "Delta", color: "pink" }
    ],
    [
      { from: "Alpha", to: "Beta" },
      { from: "Alpha", to: "Gamma" },
      { from: "Beta", to: "Beta" },
      { from: "Gamma", to: "Delta" },
      { from: "Delta", to: "Alpha" }
    ]);

demo2中代码 链接描述

 myDiagram.model = go.Model.fromJson(document.getElementById("mySavedModel").value);

请问这两种用法究竟是如何使用

看文档吧：https://gojs.net/latest/learn...，Gojs 有点难度。
