This example visualizes CSS named colors by rendering each color name as large text in its corresponding hue. It loads color data from a CSV file hosted on GitHub, which is parsed with `d3.csv`, and uses React hooks (`useState`, `useEffect`) to manage the asynchronous data fetching and component state. The visualization displays the color names as plain text strings in a single column, with each name styled using its own color value, effectively creating a self-describing color swatch list. ReactDOM renders the application into the root div, while D3 handles the data loading.
