Clustering - Fully random network

- 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). -
-
- 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. -
-
- Try values of 500 and 5000 with and without clustering. All thresholds can be changed to suit your dataset. + This example shows a fully randomly generated set of nodes and connected edges. + By clicking the checkbox you can turn clustering on and off.
