This example shows a state diagram for data loading with four states—Idle, Loading, Succeeded, and Failed—and the transitions between them. It uses Mermaid.js to parse the `stateDiagram-v2` definition and render the SVG, with custom styling applied via `styleSVGText` and `scaleSVG`. The code waits for the Inconsolata font to load using the Font Loading API before rendering, and overrides Mermaid’s default styling (text fill, font family, and label backgrounds) through CSS and JavaScript to ensure visual consistency.
