Criminal networks are known to be well organised and resilient to disruptions. This demo shows how social network analysis can play an important role in successfully damaging such a network.

Whenever items are expanded or removed, the chart will adjust the node positions adaptively.

The nodes can be removed in two scenarios. You can select one or more individuals to be “arrested” and click on Remove selected. Alternatively, you can simulate a “police raid” and Remove n largest nodes (based on degrees score), which causes even greater disruption to the network.

The nodes removed directly will ping blue, while nodes removed indirectly (by losing connection to any other node) will ping red.

Although the names are fictional, the featured data is based on a study Disrupting Resilient Criminal Networks through Data Analysis: The case of Sicilian Mafia.
