Sequence Diagram
templates.
Sequence diagrams excel when the conversation between participants is what matters: a client calling an API, services exchanging events, or two people negotiating a hand-off. The vertical axis is time, the horizontal axis is participants. Reach for one when reviewers ask "who calls who, in what order?"
