A minimal D3 starter example displays the text “Hello D3 version 7 df” in the center of the page, replacing the paragraph’s original content. The visualization uses D3 v7’s `select` API to target the `body` element and set its text content. The page loads D3 from the unpkg CDN and runs the script from `bundle.js`, with oversized font styling applied via CSS. This demonstrates the basic setup for beginning a D3 project, showing how to select an element and modify it with data-driven JavaScript.
