Today I discovered another surprise motionbilder throws at you when working with heavy scenes.
In the schematic view all nodes can be spread all over the place, in fact so far or near to each other that you are getting display errors and the graph will start flickering.
Thankfully you can script the position of these node positions.
The solution was to write a quick script to reorder them based on the hierarchy.
I hope this will help others struggling with this problem as well.
Here is the script to do this.
And yes in case you are bored out of your mind you can also arrange them in a circle. Just change line 30-39 to this.
