I'm writing a geometry package, with Points and Lines and Circles and

neither of them sits quite right with me, and I'd like the opinion of
comp.lang.python's wizened elders.
Option 1. Subclassing.
The most Pythonic way would seem to be writing subclasses for the
things I want to display, adding a ".draw(...)" method to each one,
like this:
Option 2. A "draw" function, with a function dictionary.
Option 3? Add a draw method to existing classes, rather than subclassing?
