This example renders the text “Hello VizHub!” in large, centered, 12em font using D3’s `select` to target a `div` with id `message`. The text content comes from an ES6 module, `myMessage.js`, which exports a string constant, demonstrating modular code organization. The page loads D3 v6 from a CDN and applies minimal CSS styling. The visualization simply displays static text, showing how D3 can manipulate the DOM for basic content placement.
