This example shows a finite-state machine for fetching data, with four states—idle, loading, success, and failure—and transitions triggered by FETCH, RESOLVE, REJECT, and RETRY events. The machine uses XState’s `Machine`, `assign`, and `interpret` APIs, with a `context` object tracking retry attempts. It demonstrates how statecharts handle asynchronous flows, incrementing a retry counter on each failed attempt before returning to loading. The visualization is generated by XState Viz, which renders the machine’s structure and event-driven transitions from the provided machine definition.
