I use the gri plotting language to make plots.  Does anyone here use this?

I am over my head in trying to use babel as a literate programming tool; yet
that's exactly what I need to do, else at least have a method for
coordinating better comments / notes with the code.

Gnuplot was ok when I didn't need quailty graphs.

I also need to learn to make a number of other types of plots, including
polar plots.  I understand that it is possible with gri, but haven't set
down to try to get my head around the process.
