image map question

I am searching for a script similar to mapper.js or Map Hilight which will allow me to control the colours of the map areas. I found found a few that work well but I also want to control the unactive state. This is where most fall flat. What I want to accomplish is on page load a map will appear and each map area will be a different shade of blue according to population density.

Please let me know if anyone knows of a good script I can use, che开发者_如何转开发ers

UPDATED Thanks guys, I managed to solve this using the map hilight script

what I did was actually really simple, just another case of RTFM or in this case, documentation. I used the Map Hilight script (http://davidlynch.org/js/maphilight/docs/).

In the js file there is an option: alwaysOn: true, I set this to false. Then I added this class to every area tag: class="{fillOpacity:'0.5'}"

I used the fill opacity to change the opcacity for each area based on the population density. Cheers
