This visualization displays the 148 named CSS colors as a circular pie chart, with each color represented as a slice of equal angular width. The chart loads color data from a CSV file using D3’s `csv` utility, then renders each slice as an SVG `<path>` element via React. The code uses `d3.pie` to compute arc segments and `d3.arc` to generate the path data, with each slice’s fill color taken from the dataset’s RGB hex values. The React app manages the asynchronous data loading with hooks like `useEffect` and `useState`, and renders the result inside an SVG canvas.
