This example demonstrates a minimal D3 version 6 setup by rendering the text “Hello D3 version 6” in the browser body. It uses the `select` function from the `d3` module to target the `body` element and the `.text()` method to insert the string, with `index.html` loading `d3.v6.min.js` from a CDN and the bundled `index.js` script. The page applies large 13em centered text styling to emphasize the output.
