i would like to add colorbrewer colormaps to matplotlib,
at least for my personal use, but i would like to do this
properly so that this can be used by others.
any hints on where to start? start with the cm.py module?
extend cm.py or create a stand-alone one?
the ColorBrewer palettes could be addressed by something
like one of the following, i guess?:
the colorbrewer palettes are specified by 3 to 9 rgb colors,
each interpolated differently, how many of these points would
be preferred in a matplotlib module?
...or even all of them, assuming 5seq as a default
(when using the above):
