This example demonstrates a minimal D3 v7 setup for binding an array of numbers to paragraph elements and rendering their text content. It shows how to use the `select` method alongside the data join pattern with `data` and `enter().append()`. The code creates three `<p>` elements, each displaying "Hallo" followed by a number from the input array. It loads D3 from a CDN in the HTML and relies on the `text` method to populate the content. The visualization serves as a basic starter template for learning modern D3 workflows.
