This example demonstrates a minimal D3.js visualization that displays the text "Hello VizHub!" in large, centered typography. The code uses the `select` API from D3 v6 to target the `#message` div and set its text content with data from an imported ES6 module. A separate CSS file controls the visual styling, including centering and an oversized font size. The page structure is defined in `index.html`, which loads D3 from a CDN and references the bundled JavaScript.
