This is great -- a better plotting library will make some of work a lot easier.

Nope, sorry.


Regarding Guilllaume's point, I have an unfinished library along these lines:


The basic idea is to compose images out of circles, lines, etc. much
like the new drawing library in HTDP/2e. However I'm allowing
constraints between elements -- e.g. this line must be 110% of the
width of this graphical element. I super don't have time to work on
this so if someone wants to implement this idea that would be great.

Regarding Eli's rebuttal -- *of course* it's badly designed -- it's
R!!! The idea, however, is valid.
