This example visualizes the CSS named color dataset as a radial burst of concentric, overlapping pie charts. Three separate pie arcs, built with `d3.arc`, create layered rings of colored slices, and these rings are repeated at three offset positions to form a clustered pattern. The code loads CSV data with `d3.csv` and uses React hooks like `useState` and `useEffect` to manage the data lifecycle and render the SVG. Each slice is colored directly by its corresponding hex value from the dataset, producing a vibrant, mosaic-like composition.
