An interactive donut chart displays the proportional distribution of CSS named colors, with each arc segment filled using its corresponding RGB hex value. The visualization loads color data from a remote CSV file containing named colors and their hexadecimal representations. Built with React and D3.js, the code uses `d3.pie()` to compute arc segments and `d3.arc()` to generate SVG path data, rendering the result as a single `<svg>` element centered on the canvas.
