This example uses React and D3 v7 to visualize CSS named colors as a pie chart. The application loads color data from a CSV file, then uses D3’s `pie` and `arc` functions to compute the angles and paths for each color segment. Each slice is rendered as an SVG path with a fill color matching the data’s RGB hex value, centered on a 960×500 canvas. The chart displays one equal-sized slice per color, showing the full spectrum of named CSS colors.
