This example presents a color wheel visualization of CSS named colors, split into individual arc segments representing each color. Built with React and D3 v5, it loads data from a CSV file using D3's `csv` utility and manages the data with React's `useState` and `useEffect` hooks. Each colored arc is rendered as an SVG path using D3's `arc` generator, with tooltips displaying the color keyword. The visualization maps each color to a proportional slice of the circle, providing an overview of the available named colors.
