<h2>Clustering - Fully random graph</h2>
<div style="width:700px; font-size:14px;">
This example shows a fully randomly generated set of nodes and connected edges.
By clicking the checkbox you can turn clustering on and off. If you increase the number of nodes to
a value higher than 100, automatic clustering is used before the initial draw (assuming the checkbox is checked).
<br />
<br />
Clustering is done automatically when zooming out. When zooming in over the cluster, the cluster pops open. When the cluster is very big, a special instance
will be created and the cluster contents will only be simulated in there. Double click will also open a cluster.
<br />
<br />
Try values of 500 and 5000 with and without clustering. All thresholds can be changed to suit your dataset.

<h2>Clustering - Scale-Free-Graph</h2>
