Anyone know of anything around that lets me create, and manage, a heat map of the world. Its has to be an online solution that I can host locally on a web server - Google Map solution preferred.
The way I see it working is the map, or code, makes calls (Ajax) to the database to retrieve values for a square being viewed and displays a heat map overlay on the view. Some initial settings determine values corresponding to colors.
Anyone know of anything around?
