How to highlight a region on Google Maps

问题

How can I highlight/cover a region or multiple regions with different colors (for example 3 US states), using google maps polygon arrays? I found a tuto on google code about how to draw a polygon but it's not giving detailed information.

Thank you for your help.

This documentation on Google is about as straight forward as you can get.

View the source of this page. Copy and paste the code into your own page and start from there.

In the example above you simply need to make more than one instance of bermudaTriangle and name it something else and add it to the map.
