A radial burst of CSS named colors, loaded from a CSV file and rendered as an SVG pie chart. React manages the component state and lifecycle, fetching the data with `useEffect` and `useState`, while D3 utilities `csv`, `pie`, and `arc` handle data parsing, angle calculation, and path generation. Each slice is a `<path>` filled with its corresponding hex value, centered in a 960 by 500 viewport. The code uses React 16.9 and D3 v5.
