How would I draw a simple partially transparent rectangle in python. I would like to not download anything from the internet and purely use python 2.7.3. I would like to also control where the rectangle starts and ends and control its width and height. The end goal of this is to have a map (of michigan and its great lakes) and have color coded rectangles pop up along the coast to visually show what the expected weather will be like based of buoys data from the NDBV. So in short, a map that i can place color coded rectangles on, that will be oriented along the coast of western michigan.
