This example visualizes the complete set of CSS named colors as a radial burst of pie slices, with each slice filled by its corresponding RGB hex value. The code loads color data from a CSV file using D3’s `csv` utility, then computes arc angles with `d3.pie` and renders the paths via `d3.arc`. React manages the component state and SVG output, while `useEffect` triggers the asynchronous data fetch. The visualization demonstrates a simple integration of D3’s data-processing and geometry functions within a React rendering workflow.
