Static visualizations of the call graph using various tools such as Graphviz and Gephi.
Execute pycallgraph from the command line or import it in your code.
Customisable colors. You can programatically set the colors based on number of calls, time taken, memory usage, etc.
Modules can be visually grouped together.
Easily extendable to create your own output formats.

Quick Start
Installation is easy as:
pip install pycallgraph
You can either use the command-line interface for a quick visualization of your Python script, or the pycallgraph module for more fine-grained settings.
The following examples specify graphviz as the outputter, so it’s required to be installed. They will generate a file called pycallgraph.png.
The command-line method of running pycallgraph is:
$ pycallgraph graphviz -- ./mypythonscript.py
A simple use of the API is:
from pycallgraph import PyCallGraph
from pycallgraph.output import GraphvizOutput

with PyCallGraph(output=GraphvizOutput()):
code_to_profile()
