A radial burst of 148 CSS named colors radiates from the center of an SVG canvas, with each colored slice representing one color from a CSV dataset loaded via `d3.csv`. The React component manages the data-fetching state with hooks (`useState`, `useEffect`) and renders the pie using `d3.pie()` to compute angles and `d3.arc()` to generate path geometry. React handles all DOM updates, while D3 exclusively provides the data parsing and shape-generation utilities. A loading message displays until the asynchronous CSV request resolves.
