Displaying & Modifying Diagrams / Flowgraphs in PyQt GUI

Essentially what I would like to do is draw a circuit diagram in a PyQt based on input given from another part of the GUI. My first thought was to simply use graphical tiles, and switch them out as pixmaps based on the input, but that is pretty clunky.

I supp开发者_如何学Cose finding a way to actively display dia diagrams in a frame of the GUI would work as well.

Regardless, how would you recommend going about doing this? Is there as easier way?

Thanks!

Edit: Does anyone have experience with any of the following?

• http://code.google.com/p/pydot/
• http://code.google.com/p/python-graph/
• http://code.google.com/p/yapgvb/
• http://live.gnome.org/Dia/Python

To anyone that needs to go down this route in the future, the best option was definitely pydot. Easy to use, and pretty full-featured. Way to go, Graphviz.
