Hello VizHub
This example displays a large, centered “Hello Visulization!” message in bold Ubuntu font on a dark background. It uses D3.js v5 to select the `#message` div and set its text content, while a separate ES6 module exports the message string. The page loads D3 from a CDN and applies styling through an external CSS file. The visualization demonstrates a minimal single-text display with no data-driven elements.
