title: Create a circle around a location by GET parameters only
body: <p>I need to generate a link to Google Maps, containing a location and a circle around it. I found several questions/answers related on generating URLs (e.g. <a href="https://stackoverflow.com/questions/2660201/what-parameters-should-i-use-in-a-google-maps-url-to-go-to-a-lat-lon">this one</a>).
  I'm able to display a location, use zoom factors, etc. so far (see link below).</p>
  
  <pre><code>https://maps.google.com/maps?q=39.211374,-82.978277+%28You+Were+Here%29&amp;z=14&amp;ll=39.211374,-82.978277
  </code></pre>
  
  <p><a href="https://maps.google.com/maps?q=39.211374,-82.978277%20%28You%20Were%20Here%29&amp;z=14&amp;ll=39.211374,-82.978277" rel="nofollow noreferrer">(clickable)</a></p>
  
  <p>But is it possible to add a circle with a certain radius arount the specified location? (I know it is with javascript but this is not an option).</p>
  
  <p>On a related note: is there a description of all the GET parameters available? Many answers link to <a href="http://mapki.com/wiki/Google_Map_Parameters" rel="nofollow noreferrer">http://mapki.com/wiki/Google_Map_Parameters</a>, which is not available anymore.</p>
