This example demonstrates a minimal D3 version 6 setup by rendering the text “Hello D3 version 6” in the center of the page. The visualization uses the `d3.select` API to target the `body` element and invoke its `.text()` method, with the page’s styling controlled by HTML and CSS. The code loads D3 from the `d3.v6.min.js` CDN library and executes from a separate `bundle.js` file, serving as a foundational template for starting new D3 projects.
