This gallery example displays the 148 named CSS colors as a donut-shaped pie chart using a combination of React and D3.js. The application fetches color data from a CSV file using D3’s `csv` utility, then leverages React’s `useEffect` and `useState` hooks to manage the asynchronous data loading. Each color is rendered as an SVG `path` element, with its slice geometry computed by D3’s `arc` function applied to the data array, and the transformation centers the wheel in the viewport.
