constraint

type: bool, default: true

If false, the edge is not used in ranking the nodes. For example, in the graph:

digraph G {
a -> c;
a -> b;
b -> c [constraint=false];
}

G a a c c a->c b b a->b b->c

the edge b -> c does not add a constraint during rank assignment, so the only constraints are that a be above b and c, yielding the graph:
