This example displays CSS named colors as a vertical stack of horizontal stripes, one per color, using React components to render each row. The data is loaded from a CSV file via D3’s `csv` utility, which fetches the dataset and passes it to the React app through a state hook. Each stripe’s background color is set from the `RGB hex value` field, and the layout uses inline styles for width and height. The visualization demonstrates how D3 can handle data loading while React manages the SVG-free DOM rendering.
