This example uses D3 utilities to load CSS named color data and React to render it as a radial burst of pie slices, with each slice filled by its corresponding hex value. The code loads a CSV of colors via `d3.csv`, computes the pie layout with `d3.pie`, and generates the SVG paths with `d3.arc`. React manages the asynchronous data fetch and renders the SVG elements declaratively, showing how the two libraries can work together for data-driven visualizations.
