My first Shoes app! Shoes is a "Tiny Toolkit" for informal graphics and windowing:
  http://code.whytheluckystiff.net/shoes/

I wanted to be able to easily edit Mapnik stylesheets, hit render, and see the result 
right away. While this isn't a great solution -- the prototype shells out to a C++ binary to 
re-render the map -- it works for the time being.

A screenshot of the resulting application can be seen here:

This Python code snippet demonstrates basic use of the proposed "PointDatasource" 
object exposed by the Mapnik patch attached here: http://trac.mapnik.org/ticket/113

To run this code, you will need to grab a copy of Mapnik from trunk, apply this patch, 
and also download the style.xml file below.
