This example visualizes CSS named colors as a radial pie chart, with each color occupying an equal arc segment around a central point. The code loads color data from a CSV file using `d3.csv` and manages the asynchronous loading state with React’s `useState` and `useEffect` hooks. Rendering is done via React components that produce SVG elements, with each slice drawn using `d3.arc` and fill colors set from the `RGB hex value` column in the dataset. While data loads, a simple text placeholder appears.
