Hello VizHub
This example displays a single static message, “Hello VizHub!”, centered on a dark blue background using large Ubuntu typography. It demonstrates the basic structure of a VizHub project, combining an HTML page with a linked stylesheet and a JavaScript module. The code imports the `select` function from D3.js v5 to target the `#message` div and set its text content, while the string originates from a separate ES6 module export. No dynamic data or interactive behavior is present.
