This example demonstrates the minimal setup required to render text with D3 version 7 inside an HTML page. It selects the body element and sets its content to the string “Hello D3 version 7,” while styling the page with a large font size. The code uses the `select` function from the `d3` library, which is loaded via a CDN with `d3@7.8.5`. A separate `bundle.js` script contains the logic, and the accompanying README links to a video tutorial on starting with D3 version 6.
