This example visualizes the CSS named colors dataset as a radial burst of equal-width slices, with each slice filled with its corresponding color hex value. The visualization loads data from a CSV file using the `d3.csv` utility, then renders it as SVG paths via React. Each wedge is drawn with the `d3.arc` function, which computes the path based on calculated start and end angles derived from the data index. The code demonstrates manual angle computation rather than relying on `d3.pie`, and uses React state and effects for asynchronous data loading.
