This example shows a color palette from a CSV file rendered as an SVG pie chart in React. It uses React hooks like `useState` and `useEffect` to load CSV data via `d3.csv`, then maps each row to a path using `d3.arc` and `d3.pie`. The pie slices are filled with the RGB hex values from the dataset, and the chart fills the full viewport. The implementation relies on ReactDOM for rendering and D3 v7 for data parsing and shape generation.
