Sequence Diagram Option: Visualize Variable Assignment/Reads

[MrChocolateMoose]

For sequence diagrams, it would be essential to our use case to have an additional option that would show variable assignment and reads on the diagram.

• It would interact with generate_condition_statements: true properly such that you could see control flow (e.g. a variable being set in a switch statement or through a conditional).
• It would be able to be annotated with notes the same way functions calls are able to be.
• Some consideration for local/static/global variables could be considered from a notation perspective

@MrChocolateMoose Could you include below a minimal diagram showing how this could be visualized in the diagram using PlantUML or Mermaid?

Should only be for variable assignment with values obtained from calls to function/constructor?

Or direct assignment with value should also be somehow visualized?
