title: Removing a Google maps Circle/shape
body: <p>I am creating a Circle using the google.maps.Circle() method. This all works fine and dandy, but how can I remove said circle?</p>
  
  <p>My code:</p>
  
  <pre><code>var populationOptionsAgain = {
    strokeColor: "#c4c4c4",
    strokeOpacity: 0.35,
    strokeWeight: 0,
    fillColor: "#ffffff",
    fillOpacity: 0.35,
    map: map,
    center: results[0].geometry.location,
    radius: 40000
  };
  cityCircle = new google.maps.Circle(populationOptionsAgain);
  </code></pre>
