This example demonstrates a minimal D3.js visualization that displays a static text message, "Hello VizHub!", centered on a dark blue background with large, light-colored Ubuntu typography. It shows how to combine D3’s `select` API to target a DOM element and set its text content, while using an ES6 module (`myMessage.js`) to export the message string. The page relies on D3 v5, imported via the `d3` module, and styles the output with CSS, including a Google Fonts import. No data source or dynamic rendering is involved; the example focuses on basic DOM manipulation and modular code structure.
