What diagrams have you drawn? Sequence diagrams?

Yes, I have drawn sequence diagrams to illustrate the interaction of objects over time. They help visualize the order of method calls and message exchanges between system components. For example, to describe a user authentication scenario, you can show how the client sends a request, the server checks the data, and returns a response.

A simple sequence diagram example includes objects: User, Client, Server, where arrows indicate calls and responses over time from top to bottom.
