This example demonstrates the fundamental pattern of D3.js selection and data binding by rendering three paragraph elements inside a single div. The code uses `d3.select`, `selectAll`, and `data` to apply an array of numbers `[1, 2, 3]` to the page, then calls `enter` and `append` to create the paragraphs, with `text` formatting each element’s numeric value. It relies on the D3 v5 library loaded from a CDN, paired with a minimal `index.html` structure and a CSS file that resets margins for a clean, full-bleed display.
