<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.
