I'm using graphviz (dot) to generate the graph you can see below. The node in the lower left corner (red ellipse) causes annoyance as its edges cross several edges of the adjacent node. Is there a way to restrain node placement to a certain area?

If you want to use the dot renderer. There are alternatives like neato and twopi. If graphiz isn't in your path, figure out where it is installed and run it from there.
You can change the output format by varying the value after -T and choosing an appropriate filename extension after -o.
If you're using windows, check out the installed tool called GVEdit, it makes the whole process slightly easier.
Go look at the graphviz site in the section called "User's Guides" for more detail on how to use the tools:
http://www.graphviz.org/documentation/
(See page 27 for output formatting for the dot command, for instance)
You use the label property attached to the edge.
digraph G {
a -> b [ label="a to b" ];
b -> c [ label="another label"];
}
The above generates a graph that looks something like this.

You could create an invisible constraint, to cause the red node to appear to the left of all other nodes.
