This example shows a minimal D3 version 6 starter page that displays the text “Hello D3 version 6” centered on the screen. It uses the `select` method from the d3 module to target the body element and set its text content. The page loads D3 from a CDN via the `d3.v6.min.js` script, and the code lives in an external `bundle.js` file. The styling uses plain CSS to center and enlarge the text.
