This example demonstrates a minimal D3 version 6 setup by rendering a “Hello World” message into a page element. It uses the `d3.v6.min.js` library loaded from a CDN, with the `index.js` file referencing `document.getElementById` to display the text. The HTML structure includes a styled `<pre>` tag for message output, and the code is bundled via `bundle.js`. The visualization focuses on basic DOM manipulation rather than data-driven graphics, serving as a straightforward starting point for D3 projects.
