This example demonstrates a minimal D3 version 7 setup, rendering the text “Hello D3 version 7” in the page body using the `select` method from the `d3` module. The HTML file loads D3 from a CDN and includes an external `bundle.js` script, while the CSS styles the body with 13em font size and centered text alignment. The code highlights the basic workflow of importing `select` from D3 and chaining the `.text()` method to set content, with no data source or interactive features involved.
