Displaying every available relationship rarely produces a good investigation. A useful view starts from a case and selects the entities that explain its pattern.
Start with a business question
An analyst may ask which accounts share a device, which beneficiaries receive funds from a group or which agents concentrate nearby withdrawals.
The subgraph should answer that question with a limited number of nodes, readable labels and direct access to relevant attributes.
Connect the visual to the case
Each node should expose its attributes, direct relationships and related events. The visual becomes an entry point to the facts.
A sensitive entity can be watched. A new relationship then creates a notification within the same investigation journey.
Avoid spectacle
The value of a graph lies in precise reading. Excessive animation, hundreds of nodes or ambiguous colours distract from the investigation.
A good visualisation lets the user understand a pattern, select an entity and retain evidence with few actions.
