class PolarTransform(mtransforms.Transform):
"""
The base polar transform. This handles projection *theta* and
*r* into Cartesian coordinate space *x* and *y*, but does not
perform the ultimate affine transformation into the correct
position.
The base polar transform.

This transform maps polar coordinates ``(theta, r)`` into Cartesian
coordinates ``(x, y) = (r * cos(theta), r * sin(theta))`` (but does not
handle positioning in screen space).

Path segments at a fixed radius are automatically transformed to circular
arcs as long as ``path._interpolation_steps > 1``.
