I need to create an interactive world map showing all countries. Each country needs different color settings and link to a different HTML page about that country . Also need a similar map for the US with all the 50 states. I found few websites providing a solution for this, and the imapbuilder mapping software seems easy enough to use with its map templates. However the problem is all the maps it generates are in flash format. I need a standard image map in HTML for this purpose, i.e. base on <map> tag to build a client-side image-map, so that I can use PHP to generate dynamic code. Does anyone know a simple solution for this? Open source?
