When you implement the Visualize feature, use the EntityAssociationControl control.

This control represents the relationship between the Pega Government Platform entities: Person, Business, Vehicle, and Facility, and the Investigative Case Management case instances: Event, Investigation, and Subject.

It sources the D_AssociationList data page to retrieve the associations for a particular entity and adds them as child nodes for that entity. This process repeated for the child nodes until the depth is greater than 0.
