Show All Links of full Article as Nodes

Hallo,
My colleagues and I regularly play a game where the goal is to find the shortest path between two Wikipedia articles. I found this software to enable a checking function. Therefore, I have two questions:

Is it possible to extract all links within an article using this script?
Is it possible to display all links as nodes?

I second this FR. This would make navigation a lot more useful rather than just a cool illustration.
