This example renders a colorful pie chart where each slice represents a CSS named color, loaded from a remote CSV file. The code uses React for component state management and D3’s `csv`, `pie`, and `arc` functions to compute and draw the chart as SVG paths. Each slice is filled with its corresponding hexadecimal value from the dataset, creating a full circle of distinct hues. The visualization demonstrates a straightforward mapping of categorical data to a pie layout without inner radius or additional styling.
