I am creating an application that visually displays world regions. I'm looking to develop something similar to the application at :
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)
