Hi Björn,

Sending a v2 with your suggestions.

> Or is there a reason to have it in python-xyz.scm? WDYT?

My personal preference is to have Python modules in python-* files,
similar to how python-crypto and python-web are separate from crypto
and web. But I'm not strong on this. Also, creating python-geo for this
set would seem more controversial.

As a side note, there's a problem in python-shapely that it can't find
libgeos and that will break cartopy at runtime :(

I tried out some examples from the gallery, they worked very nicely. Do
you still have problems? If so, would you fill out a bug report?

The problem was that I had an environment variable that fooled shapely
into thinking it was running from conda. I solved it by running guix
environment with --pure.

I'll send a followup series with scitools-iris later this week.
