This example displays a single, centered text message reading “Hello VizHub!” styled with large, 12em font size. The visualization uses the D3.js library, specifically the `select` API, to locate the HTML `#message` div element and set its text content. The message itself is imported from a separate ES6 module, `myMessage.js`, demonstrating modular code organization. The page’s structure is defined in `index.html`, which loads D3 v6 from a CDN and includes the local `styles.css` for typographic styling.
