This example demonstrates how to display a simple text message using D3.js and ES6 modules in a VizHub environment. It imports the `select` function from D3 and a custom `message` constant from a local module, then applies that text to a `div` element. The page is styled with an Ubuntu font from Google Fonts, a dark blue background, and large centered white text. The visualization relies on D3 v5 and standard HTML/CSS structure, with the message content defined separately in a JavaScript module for clarity.
