A simple D3.js visualization displays the text “Hello VizHub!” in large Ubuntu font on a dark background. The page initializes by selecting the `<div id="message">` element and setting its text content from a local ES6 module. The example demonstrates importing D3 functions like `select` and using modular JavaScript organization. Styling comes from an external CSS file that imports the Ubuntu font from Google Fonts. The visualization serves as a minimal template showing how to combine D3 with modular code structure and external resources.
