title: How to control node placement in graphviz (i.e. avoid edge crossings)
body: <p>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? </p>
