This example visualizes CSS named colors from a CSV dataset as a radial burst of wedges, each filled with its corresponding RGB hex value. Using React for component state and rendering, the app loads data with D3’s `csv` utility, then computes wedge geometries with `d3.pie` and `d3.arc`. The resulting SVG paths are generated in React’s declarative JSX, with the concentric layout centered on the viewport. While data loads, a loading message appears. The visualization demonstrates a hybrid approach where D3 handles data parsing and layout calculations, while React manages the DOM rendering.
