+Call Graph
+----------
+
+Pyrasite comes with a payload that generates an image of your processes call
+graph using `pycallgraph <http://pycallgraph.slowchop.com>`_.
+
+::
+
+    $ pyrasite <PID> payloads/start_callgraph.py
+    $ pyrasite <PID> payloads/stop_callgraph.py
+
+The callgraph is then generated using `graphviz <http://www.graphviz.org>`_ and
+saved to `callgraph.png`. You can see an example callgraph `here <http://pycallgraph.slowchop.com/pycallgraph/wiki/RegExpExample>`_.
