title: Change radius for a single point on Heatmap?
body: <p>Here is how you create Heatmap layer in Google Maps Api:</p>
  
  <pre><code>var data = [
          {location: new google.maps.LatLng(59.4072, 24.7053),weight:0.8},
          {location: new google.maps.LatLng(59.4372, 24.7473),weight: 1},
          {location: new google.maps.LatLng(59.4372, 24.7493),weight:0.8},
          {location: new google.maps.LatLng(59.483428, 24.841709),weight: 0.6},
          {location: new google.maps.LatLng(59.483256, 24.846666),weight: 0.2},
          {location: new google.maps.LatLng(59.409425, 27.278345),weight: 0.3}
      ];
  
  heatmap = new google.maps.visualization.HeatmapLayer({
      data: data,
      radius: 10
  });
  </code></pre>
  
  <p>As you can see, you have to specify radius in Heatmap config.<br>
  <strong>But how can I specify different radius for a single source (point) on the Heatmap?</strong> </p>
