This example displays each named CSS color as a horizontal stripe, sorted by the order in which they appear in the source CSV, creating a visual gradient of hues. The data is loaded asynchronously from a GitHub gist using `d3.csv`, while React manages the component state with `useState` and `useEffect` to render a loading message until the fetch completes. Each stripe is a styled div whose background color is set directly from the parsed ‘RGB hex value’ column, with the SVG markup in the HTML file left unused.
