Just trying to understand what's doing what and why.

Yes, I know canon = StatCanon(...) but what does StatCanon do?
Well, I'm certainly not the python expert but if we follow the trail then it seems to initialize these two classes which can be found in /lib/python/rs274/glcanon.py and /lib/python/rs274/interpret.py
rs274.glcanon.GLCanon.__init__(self, colors, geometry)
rs274.interpret.StatMixin.__init__(self, stat, random)

It looks to me that all the graphics previews are a copy of what Axis has with some variations.

Yes, with the exeption of 'Probe Basic'.It looks to me that all the graphics previews are a copy of what Axis has with some variations.
