How do I change the colour of map borders in Google Chart API?

Question

Is there a way that you can change the colour of the country borders in a map provided by Google Chart API?

As you can see, the borders stand out a bit too much for my liking.

Here's the URL if you wanted to play with it:

Unfortunately, this option is not available in the Google Chart API, as far as I know. You can always mention this feature request on the Google Chart API Group list
