Graph visualization unnecessarily wide

[leosh64]

For some networks, the visualization of the graph becomes unnecessarily wide. This makes it difficult to understand connections when zoomed in:

Throughout the model, there is no section that would justify such a wide visualization.

Below some screenshots when zoomed out:

The same issue (unnecessarily high) occurs in horizontal mode:

I was just about to report this as well!

For example, yolov5n.onnx looks like this for me:

This width is somewhat justifiable since the final layers of the model do indeed need the width, but there is no reason for the connections that go from a conv to the following mul to go all the way to the right and back.

@leosh64 @KarelPeeters @AlessandroMondin can you investigate this and suggest a fix.

dagrejs/dagre#239 has some context. The paper describing the algorithm can be found here and the code here.

Hello all, any news on this bug?
I am facing the same issue as weel:

It seems the second pass (link) of the horizontalCompaction function is related to this issue.

Tested with yolov5n.onnx.

With the second pass	Without the second pass

So my bet is everyone should edit the code to adjust the view when needed.
