But I had deleted it after I just did it from scratch for an internal project, using a simpler approach. The original C++ lib was https://github.com/nbergont/qgv It lists a decent talk about how to use graphviz for this purpose http://www.mupuf.org/blog/2010/07/08/how_to_use_graphviz_to_draw_graphs_in_a_qt_graphics_scene/ If I manage to find the PySide version I did, I will share it.
