This example displays the text “Hello VizHub!” prominently in the center of a dark blue page, styled with the Ubuntu font. The visualization demonstrates a minimal D3.js setup, using the `select` API to target an HTML element and set its text content. The message itself is defined in a separate ES6 module, which is imported into the main script, showcasing modular code organization. The page relies on a CSS file for visual styling and pulls D3 version 5.9.1 from a CDN.
