title: Creating shaded areas for distances in the Google Maps API
body: <p>I need to show my clients what 'zone' they live in (how much they will pay depending on how far away they are from my business).  I want to use Google Maps to give them a view of what roads/towns/cities/etc. are in what zone.  I was going to make some kind of definable barrier of sorts that would emanate from the center point.</p>
  
  <p>I would have it so one barrier line showed where it was <code>x</code> miles away from the center point, another barrier would define areas <code>y</code> miles away, another defining areas <code>z</code> miles away, and so on and so forth.</p>
  
  <p>I've never used the Google API and I'm only slightly good at Javascript...  What is the best path to take here to learning how to do this... or... even better... how would I do this?</p>
  
  <p>Thanks for helping!</p>
  
  <p>Cheers!</p>
