This example visualizes CSS named colors as a radial burst, where each color is represented by a slice of a pie chart. It loads color data from a CSV file using D3's `csv` utility, then computes the arc paths with `d3.pie` and `d3.arc`. React handles rendering the SVG paths, while D3 manages the data parsing and geometry. The final output is a colorful circular layout that displays the full spectrum of named web colors.
