I am creating an application that visually displays world regions. I'm looking to develop something similar to the application at : http://users.rcn.com/smallpond1/ (map.pl)

I have been able to locate some datasets (shapefile) at http://www.gadm.org/. However, I do need some help putting it all together. I have read the documentation at the CPAN page but I need some demos in the form of examples.

Basically, I require your guidance on how to extract the coordinates information and plot it as given in the map.pl script. (Probably a demo script if its not too much to ask. Just to get an idea)

Your help is much appreciated...!! Thanks in advance
