A minimal D3.js example renders the text "Hello VizHub!" inside a single HTML div. The visualization demonstrates a basic D3 workflow by importing the `select` function from the D3 library and using it to target the `#message` element. An ES6 module, `myMessage.js`, supplies the string content, while `styles.css` centers the text with a large font size. The HTML loads D3 from UNPKG, local CSS, and executes the compiled JavaScript bundle.
