title: Connecting arcs between lines in Dot (GraphViz)
body: <p>I've got to do up a state space graph for my AI course, and I was hoping to use GraphViz to make it (so much faster than Dia). The one thing I can't seem to figure out how to do is how to do an "And" connection, which is basically an arc between two lines connecting to the same node. Is this possible? </p>
