A color visualization renders the 148 CSS named colors as horizontal stripes, sorted in the order they appear in a CSV file loaded from a GitHub gist. The example demonstrates React’s component model by mapping each row of data to a `<div>` whose background color is set from the `RGB hex value` field. D3’s `csv` utility fetches and parses the data, while React’s `useState` and `useEffect` hooks manage the asynchronous loading state, showing a “Loading…” message until the data arrives. The result is a simple, full-width gradient-like display of all named colors in SVG-less, div-based rendering.
