Visualizing Data with Reach and D3
This example visualizes CSS named colors as a radial burst, with each color represented by a wedge of equal angular size arranged around the center. The code loads the color data from a CSV file using `d3.csv`, then uses React hooks (`useState`, `useEffect`) to manage the asynchronous data loading and trigger a re-render. D3’s `pie()` and `arc()` generators compute the wedge shapes, which are rendered as SVG `<path>` elements with fill colors taken directly from the dataset’s hex values. The visualization updates dynamically once the data arrives, showing the full spectrum of named colors in a compact, circular layout.
