This visualization displays the CSS named colors as a pie chart, with each slice colored according to its corresponding hex value. The chart renders all color categories as equal-sized arcs using React to manage the data loading state and D3’s `csv` utility to fetch the dataset from a GitHub gist. Slices are drawn with `d3.arc` and `d3.pie` methods, producing an SVG output inside a React component. The example demonstrates a straightforward integration of React for UI state with D3 for data parsing and geometric layout.
