This example presents a simple interactive scene using an embedded YouTube video within a bare-bones HTML page. The main visualization is a video player that users can control directly. The page’s code, primarily in `index.html`, likely relies on the standard HTML `<iframe>` element and the YouTube player API for playback. No additional data sources or complex rendering libraries like D3 or Three.js are present; the focus is solely on embedding and displaying a single video via the provided URL.
