This example renders CSS named colors as a radial burst of pie slices, with each slice filled by its corresponding RGB hex value from a CSV dataset loaded via D3’s `csv` utility. React state manages the asynchronous data loading, while D3’s `pie` layout and `arc` generator compute slice geometries for SVG `<path>` elements. The visualization demonstrates a hybrid approach where React controls rendering and lifecycle, and D3 handles data parsing and shape math.
