django web-applications graph graphviz pydot

I am trying to make a few interactive graph visualisations in my Django web application using Python. I found Graphviz and was able to output a static graph (as a .png image) on my application using Pydot (Python interface to Graphviz's dot language).

However, I am looking to make my graphs more interactive, like being able to highlight nodes when passing my mouse over it, making the nodes click-able, dragging the nodes to a different location and zooming on the graph.

Is there a way I could do this in Graphviz? Or in general is there way to make an interactive graph for my Django application without having to use Flash? I don't want to use flash since I'm not that familiar with it and also since I want to visualise a fairly large dataset.

Try The Javascript Infovis Toolkit. It is all implemented in a browser canvas, so no Flash is needed, only a decent browser with support for the <canvas> tag. Graph visualization examples are here, here and here, other demos are here.
