This example displays the static text “Hello D3 version 6” centered on the page at a very large font size, serving as a minimal introductory demonstration. The page loads D3 version 7 from a CDN and uses the `select` function to target the `body` element, then calls `.text()` to set its content. The code relies on a separate `bundle.js` file to execute the main script, while the HTML structure is kept intentionally bare to highlight D3’s direct DOM manipulation.
