This example displays a color wheel of CSS named colors, with each color rendered as a wedge-shaped path arranged in a circular layout. It loads color data from a CSV file using `d3.csv` and renders the visualization with React components and SVG paths. The `d3.arc` generator computes the wedge shapes, while React’s `useState` and `useEffect` manage the asynchronous data loading and component rendering. The color fill for each path comes directly from the RGB hex value column in the dataset.
