I whipped together a quick Python script to do this. Attached is the
Python script (requires pydot) and the result of running it on includes/.
I didn't attach the png version of the output because it was 7MB.

If rendering all includes at once doesn't give a good overview it can
also select a subset through traversing dependencies. For example:
render_includes.py -i include/ \
  --select="storage/spin.h+*,access/xlog.h+*" output.png

This will render everything that directly or indirectly depends  on those
two headers. See --help for details.
