[[!template id=gitrepo repo=call_graph]]

This script scans a Python file for function dependencies, and
generates code for [Graphviz dot][graphviz].  See [[depgraph]] for
scripts to generate dependency graphs *between* modules.

Originally by [Prashantha Ellina][original], the [script][call_graph]
is good for giving you the "short view" for restructuring a single
module.

[[!template id=gitrepo repo=calibrate_cantilever]]

As example, here is the callgraph of my cantilever calibration program
`calibrate_cantilever.py`.

    $ python construct_call_graph.py -i calibrate_cantilever.py | dot -T png -o call_graph.png

[[!img call_graph.png class="scaled"
  alt="calibrate_cantilever.py call graph"
  title="calibrate_cantilever.py call graph"]]
