D3.js!
This example demonstrates the fundamental data-join pattern in D3.js, where an array of numbers [1, 2, 3] is bound to a selection of paragraph elements. Using `d3.select`, `selectAll`, `data`, `enter`, and `append`, it creates three `<p>` elements inside a `<div>`, with each paragraph’s text set to the corresponding data value via `.text(dta => dta)`. The code runs in a React environment while loading the D3 v7 library from a CDN, highlighting how to mix D3’s imperative DOM manipulation with a minimal HTML page structure.
