[Matplotlib-users] schematic diagrams - fancy boxes, packers and arrows

[John H. <jd...@gm...>]

This is mainly a question for JJ.  I would like to make a schematic
diagram, like you might get from Dia or OmniGraffle.  With the offset
boxes, annotations, vpackers/hpackers and fancy arrows, it seems like
the pieces are mostly in place.  Unlike simple annotations, I need to
have multiple arrows originating from a single box.  The diagram I am
trying to draw shows the relationship between various packages for
scientific computing in python.  The crude ASCII art picture looks
like this:


            Python
          /         \
         /           \
    IPython          Numpy
         |        /   \
         |       /     \
       matplotlib     scipy

where arrows are pointing from

  Python -> IPython
  Python -> numpy
  IPython -> matplotlib
  numpy -> matplotlib
  numpy -> scipy

and IPython and numpy are on one level (HPacker?) and are below Python
(Vpacker?) and so on.  Each text instance is surrounded by a fancy box
and are connected by fancy arrows.

Is it fairly easy to put something like this together using all the
offsetbox tools and fancy arrows?

Thanks,
JDH
