Hello VizHub
A minimal D3.js v5 example renders the text "Hello VizHub!" in a large, centered Ubuntu font against a dark navy background. The page loads D3 from a CDN and uses the `select` API to target the `#message` div, setting its text content. A local ES6 module exports the message string, while an external stylesheet defines the visual presentation with Google Fonts and CSS properties. The example demonstrates basic DOM selection, module imports, and stylesheet integration within the VizHub environment.
