This example displays a simple "Hello VizHub!" message centered on the page. It demonstrates a minimal D3.js setup by using the `select` function from D3 to target the `#message` div and set its text content. The text is styled with large, centered font via the accompanying `styles.css`. The code imports the `message` string from a local module, `myMessage.js`, and renders it, showing how to structure a basic visualization app with external styles and modular code.
