This example demonstrates the most basic possible D3.js setup: a single line of text reading “D3.js version 6” centered on a blank page. The code uses the `select` function from the d3 library to target the `<body>` element and the `.text()` method to insert the string. The page loads D3 version 6 directly from a CDN, and the JavaScript is bundled into `bundle.js` via a separate build step. No data is loaded or manipulated; the example serves solely as a minimal entry point for verifying a D3 installation works.
