Dear all,
The example shows this:

  myGuests.model = new go.GraphLinksModel([
    { key: "Tyrion Lannister" },
    { key: "Daenerys Targaryen", plus: 3 },  // dragons, of course       
    { key: "Hodor" }
  ]);

Using “key” as a text to display. Now I want to re-define this structure like this

  myGuests.model = new go.GraphLinksModel([
    { key: "1", name: "Tyrion Lannister" },
    { key: "2", name: "Daenerys Targaryen", plus: 3 },  // dragons, of course       
    { key: "3", name: "Hodor" }
  ]);

and use key as ID(identify) and name for displaying.
