A radial burst visualization of CSS named colors, rendered as an SVG donut chart using React for component structure and D3 utilities for data processing and shape generation. It loads color data from a CSV file via `d3.csv`, then uses `d3.pie` to compute arc angles and `d3.arc` to generate the path geometry, with each slice filled by its corresponding hex value. React's `useState` and `useEffect` hooks manage the asynchronous data loading and re-render the chart once the data arrives.
