Description

For example, rectangles should easily translate to arc mark, but they currently don't.

VISUALISE Day AS x, Month AS y, Temp AS fill FROM ggsql:airquality
  DRAW rect
  PROJECT x, y TO polar

Research direction

Start by reproducing the supplied ggsql:airquality example and trace how the DRAW rect mark is handled after PROJECT x, y TO polar. Inspect the polar-coordinate and mark-conversion paths to determine how discrete position scales should map rectangles to arcs. Done means the example renders rectangles as arc marks in polar coordinates, with coverage for the behavior.
