This example demonstrates loading CSS named color data from a CSV file using D3’s `csv` utility, with React state managing the asynchronous data fetch. Once the data arrives, the application renders a collection of SVG paths, each representing a color through a mouth-like arc shape. The code uses React hooks like `useState` and `useEffect` to trigger and store the data, while the SVG rendering relies on `d3.csv` for parsing and React’s declarative component structure. A loading message appears until the data is ready.
