objgraph is a module that lets you visually explore Python object graphs.

You'll need graphviz if you want to draw the pretty graphs.

I recommend xdot for interactive use. pip install xdot should suffice; objgraph will automatically look for it in your PATH.

pip install objgraph or download it from PyPI.

Documentation lives at http://mg.pov.lt/objgraph.

I've developed a set of functions that eventually became objgraph when I was hunting for memory leaks in a Python program. The whole story -- with illustrated examples -- is in this series of blog posts:

• Hunting memory leaks in Python
• Python object graphs
• Object graphs with graphviz

The source code can be found in this Git repository: https://github.com/mgedmin/objgraph.
