title: Openlayers 3 - Clustering & Lines as a combination
body: <p>My aim is to cluster many coordinates in the view. This points also can have "connections" between them which I want to show as a LineString.</p>
  
  <p>I tried a lot but I cannot find a way to integrate the Lines into the Cluster.</p>
  
  <p>My current (stable) status can be seen here:
  <a href="http://jsfiddle.net/6RS2z/467/" rel="nofollow">Fiddle</a></p>
  
  <pre><code>var clusterSource = new ol.source.Cluster({
    distance: 20,
    source: vectorDevices
  });
  </code></pre>
  
  <p>If the two points "merge" into the cluster it would be great if the conntection disappears or is part of the cluster itself.</p>
  
  <p>Can anyone help me?</p>
  
  <p>I tried to add the vectorLine as a source to the Cluster

  <pre><code>var clusterSource = new ol.source.Cluster({
    distance: 20,
    source: [vectorDevices, vectorLine]
  });
  </code></pre>
  
  <p>or via addFeature 
  <a href="http://jsfiddle.net/6RS2z/469/" rel="nofollow">fiddle</a></p>
  
  <pre><code>clusterSource.addFeature(vectorLine);
  </code></pre>
