This seems OK.  It's written as a one-off w/o much re-use in mind, which is kinda the opposite of how I try to write python. :)  I think this could use another round of cleanup to make this more hackable for others in the future.

I'm glad you're adding this though. :)

I think pep8 says two spaces between globals, but I could be wrong.

> +        global hotspot
> +        global scaleSize
> +        global showBars

Seems this could just take an options object instead of using globals.

I would have broken this up into smaller functions.

Seems long-winded.

In general this is fine.  We should land this and iterate.
