This example demonstrates the minimal setup required to render text with D3 version 7, displaying the message “Hello D3 version 7” centered on the page. The code uses the `select` function from the D3 module to target the `body` element and the `.text` method to inject the string. The HTML file imports D3 via a CDN script tag, while the JavaScript is bundled separately into `bundle.js`. Styling relies on inline CSS to enlarge the font size and center the content horizontally.
