title: Zip Code Boundaries Using Google Maps Api
body: <p>I need to display google map with zip code boundaries like this</p>

  <p>Perhaps I am overlooking it, but I've not been to find examples of this and documentation talking about this specifically at Google Maps API documentation. I've trying doing a view source on the above web page link, but it doesn't seem obvious to me how it works. There is also other stuff on the page which I don't know if it's part of what I need or not.</p>
  
  <p>Some simple code examples would be very helpful! Thanks!</p>
