I need to build a custom interactive web map of my country with all it's regions (Peru). Which tool or technology would be the best way to go?
The idea is to have a map that shows the population of each region with a color scale: the more people the region has, the darker it's painted. Also I need to display some information as text and pictures when I click each region as the maps zooms in.
I've seen around and there are lots of "pre-developed" tools that can be customized but I need to build my own. Flash is already discarded. I was thinking of Java applet but is just an idea. Thank you for your answers.
System requirements: Apache+PHP+MySQL
