This example displays a static, large "Hello VizHub!" message centered on a dark background using the Ubuntu font. The page is built with a minimal HTML structure, where D3 v5’s `select` method targets a `div` and sets its text content to a string imported from a local ES6 module. Styling is handled entirely through CSS, including the background color, text alignment, and font size, while the D3 library is loaded via a CDN.
