This example renders a centered “Hello VizHub!” message using D3 version 6. The index.js script imports the `select` function from D3 and sets the text content of the `#message` div to a string imported from a separate ES6 module, `myMessage.js`. The message is styled with large, centered font via the `styles.css` file, demonstrating a minimal setup of D3 for DOM manipulation alongside modular JavaScript.
