This example displays the text “Hello VizHub!” centered on a dark gray background, with the message rendered in a large, Ubuntu font. The visualization uses D3.js version 5, specifically the `select` API to target a `div` element and set its text content from an imported ES6 module. A separate CSS stylesheet defines the page’s color scheme, typography, and text alignment, while the HTML file loads D3 from a CDN and runs a bundled JavaScript file that combines the main script and the message module.
