This example displays 148 CSS named colors as a vertical striped column, where each stripe's height and color correspond to a row in a CSV dataset loaded from a Gist. The visualization uses D3’s `csv` function to fetch and parse the data, then React's `useEffect` and `useState` hooks manage the asynchronous loading and rendering. Each color is drawn as a `<div>` element with its background set to the hex value parsed from the dataset, producing a simple, sequential swatch layout.
