How to add edge labels in Graphviz ?

Question

Hi,

I am trying to draw a graph using Graphviz, but I need to add labels on the Edges. There does not seem to be any way to that in Graphviz. Are there a way out?

Answer 1

You use the label property attached to the edge.

digraph G {
 a;
 b;
 c;
 a -> b [ label="a to b" ];
 b -> c [ label="another label"];
}

The above generates a graph that looks something like this.
