A colorful pie chart displays all 148 CSS named colors as equal slices, rendered as SVG paths within a React component. The visualization uses D3's `pie` and `arc` functions to compute angles and paths from a CSV dataset of CSS color names and their hex values. Data is loaded asynchronously via D3's `csv` function from a remote gist URL. The React app shows a loading message until the data arrives, then renders the pie chart centered in an SVG canvas.
