This example renders an SVG visualization of CSS color names using React and D3. It loads a dataset of named CSS colors from a CSV file via `d3.csv`, then maps each color to an arc path using `d3.arc`. The arcs are arranged in a spiral pattern inspired by the Fibonacci sequence, with the colors displayed according to their hex values. The React component manages loading state and renders the SVG paths dynamically, demonstrating how to combine React’s component model with D3’s data utilities for declarative data-driven graphics.
