A radial burst of CSS named colors is rendered as a pie chart, with each wedge filled by its corresponding hex value. The visualization demonstrates combining React for component state and rendering with D3 utilities for data processing and shape generation. React’s `useEffect` and `useState` hooks fetch and store the CSV data, while `d3.csv`, `d3.pie`, and `d3.arc` compute the angular layout and path geometry. The chart uses SVG output, with a loading message shown before data arrives.
