there is a codevis application in the open for almost two years. it generates large scale software visualization for c, c++ and fortran (but it accepts other languages as plugins).
i am the main developer of this tool, and im a bit shocked that another tool with similar intent and same name exists.
woyod you be ok for me to demo what codevis (the kde one) do to your team?
you can reach me at tcanabrava at kde.org
the source of codevis is at invent.kde.org/sdk/codevis
