State Machine Diagrams

State Machine Diagrams visually represent how an object or system changes through different conditions or modes over time. They show states (statuses the system can be in) and transitions (the events or conditions that cause movement from one state to another). These diagrams help in understanding the lifecycle of an object, such as a user login process, by depicting states like "logged out," "logging in," and "logged in," along with the triggers that change states. They are useful for designing, analyzing, and troubleshooting dynamic behavior in software and systems.
