This example displays the text “Hello D3 version 7” centered on a blank page at a very large font size, demonstrating a minimal setup for a D3 v7 project. It uses the `select` function from the `d3` module within `index.js` to target the body element and set its text content. The page loads D3 from a CDN and the script runs via a bundled file, following the starter template’s approach of blending a simple HTML structure with a separate JavaScript entry point.
