title: How to make a parallelogram shaped vertex in JGraphx?
body: <p>I'm trying to display a flowchart via JGraphx, and I need a parallelogram for input/output block. But JGraphx doesn't seem to know "shape=parallelogram". It seems odd not to have a parallelogram in a library for graphs and flowcharts (and it even has "actor" shape, how come it doesn't have a parallelogram?). Maybe it's only named some other way? Or in the case there is indeed no predefined parallelogram shape, what do I do to make a vertex into parallelogram?</p>
