This example visualizes the state machine of the VizHub Runtime Environment as an interactive Mermaid diagram, illustrating four states—IDLE, ENQUEUED, PENDING_CLEAN, and PENDING_DIRTY—and their transitions triggered by code-change events and build completion. Built with the Mermaid library (mermaid.render), it uses a stateDiagram-v2 definition embedded directly in an HTML page, with custom CSS and themeVariables for styling nodes, edges, and gray note boxes. The diagram animates through state transitions on load, conveying the runtime’s logic for handling concurrent code changes during builds.
