This example demonstrates the basic D3.js pattern for binding an array of data values to HTML elements and appending new elements to the DOM. Using the `d3.select`, `selectAll`, `data`, `enter`, and `append` methods, it creates three `<p>` paragraphs inside a `<div>`, each displaying its corresponding data value as text. The code relies on the v5 release of the d3.js library, loaded via a CDN link in the `index.html` file, and uses an `app.js` script to perform the selection and binding operations.
