state diagram

A state diagram is a visual tool used to show the different conditions or situations an object or system can be in, and how it transitions between these states over time. Think of it like a flowchart for the status of something, such as a traffic light changing from green to yellow to red. Each "state" represents a specific condition, and the arrows indicate actions or events that cause the system to move from one state to another. It's useful for understanding and designing systems that have predictable behaviors based on different inputs or events.
