I'm doing a similar thing with the R statistics programming
environment. The R code writes an include file with the
statistics that I want rendered, then at the end it calls
(executes) pov SDL that generates a pretty graph.

Here is what I use in R:

(beware if this wraps)
system('C:\\progra~1\\pov-ra~1.5\\bin\\pvengine.exe C:\\Rpovray.ini
C:\\Rpovray.pov')

The location is standard for a Windows installation.
The double "\\" is because R uses "\" as a control character.
