This example shows a pie chart of CSS named colors, rendered as an SVG using React and D3. It loads color data from a CSV file via `d3.csv`, then uses `d3.pie` and `d3.arc` to compute and draw the pie slices. Each slice’s fill color comes directly from the `RGB hex value` column of the data. The chart is centered within a fixed 960×500 viewport, with React managing the loading state and rendering the SVG elements.
