==========================
Scatter plot on polar axis
==========================

Size increases radially in this example and color increases with angle
(just to verify the symbols are being scattered correctly).

Scatter plot on polar axis, with offset origin
----------------------------------------------

The main difference with the previous plot is the configuration of the origin
radius, producing an annulus. Additionally, the theta zero location is set to
rotate the plot.

Scatter plot on polar axis confined to a sector
-----------------------------------------------

The main difference with the previous plots is the configuration of the
theta start and end limits, producing a sector instead of a full circle.
