This example demonstrates loading and parsing CSV data using the D3 `csv` function within a React application. It fetches a gist containing CSS named colors and renders each row as a 100x100 pixel square with its background color set to the `RGB hex value` from the data. The component initially displays a "Loading..." message until `setData` is called, then maps over the parsed array to create the color swatches. The code uses React hooks (`useState`, `useEffect`) and imports `csv` from `d3`.
