title: Drawing Graphs ALA Graphviz in QT via PyQt4
body: <p>I need to draw Concept networks(nodes - edges - nodes can have text properties) from a data model and have it layed out nicely (using QT). I already have experience with graphviz, but i'm willing to learn something else if it works outa-da-box. What are my options ? I know I could generate a image and then draw that via a QLabel somehow. However, I am hoping there is a nice integrated API available that simplifies this ? </p>
