UnifiedModelingLanguage (UML) diagrams that show the interaction of object instances over time. Two forms for the same data:
  1. SequenceDiagram (Wiki MessageSequenceChart) -- emphasizes the flow of time; what messages are sent in what sequence.
  2. CollaborationDiagram -- emphasizes the relationships between objects. Clusters of arrows show heavy communication between instances. Shows "spatial" relationships between objects, much like a class diagram.
(Both shown at the URL on the top of this page.)
