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
