This example displays CSS named colors as a horizontal stacked bar chart, where each color appears as a thin stripe in sequence. The visualization uses React to manage component state and rendering, while D3’s `csv` utility loads the color data from a remote GitHub gist. Data is fetched asynchronously with React’s `useEffect` and `useState` hooks, and the hex color values directly set each stripe’s background color. The code also includes commented-out logic for computing radial arcs using D3’s `arc` and `pie` functions, though the active rendering uses simple divs.
