Rendering as a binning process for Python 3

 In most visualization systems, the pixels are tucked away under
 levels of geometric abstraction in the rendering system (such as
 circles, squares, and text). Abstract Rendering takes the opposite
 approach: expose the pixels and gain powerful pixel-level
 control. This pixel-level power is a complement to many existing
 visualization techniques. It is an elaboration on rendering, not an
 analytic or projection step, so it can be used as epilogue to many
 existing techniques.
