This example visualizes the CSS named colors dataset as a radial burst, with each color represented by a wedge-shaped slice in a circular SVG layout. The visualization loads data from a CSV file using D3’s `csv` utility, then employs React’s `useState` and `useEffect` to fetch and store the data. React renders each arc using D3’s `arc` and `pie` functions, generating paths filled with the hex values from the dataset. The code runs within an HTML page that imports React 16, ReactDOM, and D3 v5 via CDN.
