How can I prevent edges fron crosing?

I'm having the same problem, if I understand the question correctly.

Unfortunately it is not possible by default. You have to implement custom edge routing algorithm.

Is it possible instead to increase the distance between vertices from one level to the next or previous one? Maybe based on children number. I thought that by increasing vertical distance I could obtain straight edges or in any case not overlapping.
