Hello VizHub
This example displays a single, large "Hello VizHub!" message centered against a dark blue background. It uses D3 v5’s `select` function to target the `#message` div and set its text content, pulling the string from a separate ES6 module. The page’s styling relies on the Ubuntu font from Google Fonts, applied via CSS. The visualization is purely textual, demonstrating basic DOM manipulation and module imports within the VizHub framework.
