Statechart diagrams

Statechart diagrams are visual tools used to represent how a system or object behaves over time, showing different states it can be in and how it transitions between them based on events or conditions. They help illustrate the lifecycle of an entity, such as a device or process, by mapping out states like "idle," "processing," or "error," along with the triggers that cause changes. These diagrams make it easier to understand complex behaviors in systems, especially those that depend on multiple states and transitions, providing clarity on how the system responds to various inputs or situations.
