What do you mean by “display”?

If you want to highlight some existing links or nodes, please read GoJS Highlighting -- Northwoods Software

If you search for samples that make use of those methods, you will find some example usage.

What is it that you are trying to do? It would really help if you provided small screenshots or sketches of what you want at each step.

Have you read GoJS SubTrees -- Northwoods Software ?

Normally when a Node is not visible all connected Links are also not visible. If you want a Link to remain visible even though one or both connected Nodes are not seen, you should not set Node.visible to false but instead set Node.opacity to zero.
