What you can model
Interaction overview diagrams provide high-level control flow that points to more detailed interactions. Readers see the order of scenarios without every message on one canvas.
How to use this maker
Outline major interaction steps as actions, branch on outcomes, preview the map, then export and link readers to dedicated sequence diagrams for detail.
Notation that matters
Nodes often represent interactions or interaction uses, not only atomic actions. Control flow connects those interactions much like an activity diagram, but the content of each node is a scenario reference.
Keep the diagram readable
Do not paste full message lists into the overview. Keep this page as a map. Use activity diagrams for single-process steps, and sequence diagrams for the detailed hops inside each referenced flow.
Frequently asked questions
Is this interaction overview diagram maker free?
Yes. Create and export online without a paid plan.
How is this different from an activity diagram?
Nodes often represent interactions or interaction uses, not only atomic actions in a single process.
When should I skip this diagram?
If you only have one short sequence, draw that sequence directly. Overviews help when several scenarios must be ordered together.
