How can I make maybe 3D subfigures with Python and matplotlib?
I found the following example (http://matplotlib.sourceforge.net/
examples/mplot3d/subplot3d_demo.html), but it doesn't work.

Cobra seems interessant, open-source, but the dependance on Mono and
.Net annoy me a bit.
Otherwise, cobra have good ideas, a syntax similar to python.
One thing i really love is the "How-To" and the "Samples" pages on
it's website, i think it's a very good thing for beginners.

I adopted Py3 because of support of OrderedDict and many new features.
Since mine was a new project using no existing libraries, it made
sense.
