graphviz with combined edges

graph-theory, graphviz

Solution

you must introduce intermediate (eventually hidden) nodes to act as split points. For instance:

digraph G {
 graph [rankdir=LR,splines=ortho,concentrate=true];
 node [shape=box,];
 edge [dir=none];
 i [shape=point];
 a -> i -> b;
 a -> i -> c;
}

yields

Problem

I'm looking for a way to achieve something like this in graphviz: ``` --- node B | node A --- | --- node C ``` another example (at the bottom): http://machining.grundfos.de/media/60727/grundfos_pumpenhandbuch.pdf#23 Is there a way of doing that with graphviz? so far I only got orthogonal edges: ``` digraph G { graph [rankdir=LR,splines=ortho,concentrate=true]; node [shape=box,]; edge [dir=none]; a -> b; a -> c; } ```
