This example demonstrates the minimal setup required to render text with D3 version 7. It uses `d3.select` to target the body element and the `.text` method to insert the string "Hello D3 version 7" directly into the page. The HTML includes the D3 library from a CDN and references a separate `bundle.js` file, while CSS centers the text at a large font size. The visualization shows a simple, static output with no data or interactions.
