Graphviz: make edges not affecting the hierarchy of nodes

Question

I add edges (green) to graph, that makes hierarchy of nodes. How to add minor edges (red) that not affecting on the hierarchy?

Answer 1

If you want an edge to not have an impact on ranking, you can simply set the constraint attribute to false:

If false, the edge is not used in ranking the nodes.

Example:

node1 -> node2 [constraint=false];
