Google Map Color Coding Countries based on marker value

I need to color code counties on my google maps based 开发者_运维知识库on the markers on these locations. Anyone with some idea as to how this can be done? I am using google earth

I can create markers dynamically and show my data. Now I need to find a way to style google maps.

As of right now Google does not support county shading it seems. With map charts here, it lets you shade countries and states.

The closest I've got to seeing county shading is an example here:

You can read a little bit about how it was made here: http://www.lazylightning.org/minnesota-county-kmz-overlay-for-google-maps

I'm not sure how extensively you can customize Google Earth, but if you're not dead-set on it, try one of these: Google Visualizations

Depending on which one you choose (I believe there are three different types of maps available,) there are loads of customization possibilities. Also, none of these require a proprietary plugin like Google Earth does (just Javascript and Flash. Okay, Flash is a proprietary plugin, but I'm sure it's far more common than the Google Earth plugin.)
