improve initial question layout

[cbizon]

Try some 1 and two hops with predicates. The nodes are frequently overlapped and the edges are usually unreadable until the nodes are moved around.

Is this for the aggregate graph view? Do you have a sample message for me to test with?

[cbizon]

No, for the question view. Pretty much any of the questions in the notebook here: https://github.com/ranking-agent/QuestionRewrite/blob/master/documentation/QuestionAugmentationEdges.ipynb

So the original 1-hop looks like this:

Note that the predicate is hidden behind n0

A little further down, a 3 hop looks like this:

Besides the kind of odd layout, there are overlapping nodes.
