A minimal demonstration of a D3 starter template, this example renders the text “Hello D3 version 7” directly in the browser body using D3’s `select` method. The page imports the D3 v7 library from a CDN and uses a separate `bundle.js` file to execute the JavaScript logic. The styling is kept intentionally simple, with centered, oversized text, to focus on the basic setup and the transition from D3 version 6 to version 7.
