Sometimes it would be very cumbersome to re-create a floorplan map
using x/y coordinates and polygons. In cases like that, here is an
alternate technique where you can use an image of the floorplan 
(such as a png or gif file), and use the x-pixels and y-pixels 
dimensions of the image as your x/y coordinate system, and then
annotate colored markers/etc on the image to represent the data.

You might use this technique to plot data on maps such as 
malls, hospitals, dorm rooms, prisons, offices, etc.

This particular example is a simplified case, where I'm plotting
one demo station location in the SAS Global Forum demo room.
