Hello VizHub
This example displays the text “Hello VizHub!” centered on a dark, gray background. It demonstrates a minimal D3.js setup, using the `select` function to target a `<div>` element and set its content. The page loads D3 v5 from a CDN and imports a custom ES6 module to supply the message string. Styling is handled with CSS, including a Google Fonts import for the Ubuntu typeface.
