This example shows a React-driven visualization that renders CSS named colors as individual SVG paths, with each color represented by a filled shape. The app loads color data from a CSV file using D3’s `csv` utility, then uses React’s `useState` and `useEffect` hooks to fetch and store the data asynchronously. ReactDOM renders an SVG containing one `<path>` per color, filling each with its corresponding hex value from the dataset. The code also includes a separate message module that reports file size, row count, and column count, though it is not displayed in the final output.
