A minimal "Hello VizHub" example displays a large, centered greeting message in bold Ubuntu type on a deep blue background. The page uses D3 v5’s `select` function to set the text content of a `div` with the ID `message`. The message string is imported as an ES6 module from `myMessage.js`, demonstrating modular code organization. Styling comes from a linked CSS file that sets typography and color, while `index.html` loads D3 from a CDN.
