This example visualizes all named CSS colors as a vertical stack of thin horizontal bars, each colored according to its corresponding RGB hex value. It loads color data from a CSV file using D3’s `csv` utility, stores the fetched array in React state via the `useState` and `useEffect` hooks, and renders each row as a styled `div`. While the data loads, a large "Loading..." message appears. The visualization highlights the sequential ordering of the color list and demonstrates a simple React–D3 data-fetching integration without any charting library.
