I have a graph which is very strongly linked, which means looking at its nodes can be visibly confusing, and impossible to understand anything.I'm looking for a way to make it easier to look at a few nodes which were selected by the user.
Does your data have any logical grouping? If so, then maybe subgraphs can help.
Do you have a screenshot to show what you mean?
Maybe you want to change the default GoLink.Pen to be Pens.LightGray, and change links that have both nodes selected to be Pens.Black. The WebWalker sample exhibits this, but does not change any pens based on selection.
