This example demonstrates rendering a dataset of CSS named colors as a series of horizontal stacked bars, each colored by its corresponding RGB hex value. The visualization uses React to map each data row to a div element, with the background color set directly from the CSV field. D3’s `csv` function loads the color data asynchronously from a GitHub gist URL, while React’s `useState` and `useEffect` hooks manage the loading state. Once fetched, the app renders a full-width strip of colored segments, with a loading message displayed until the data arrives.
