This example demonstrates how to load external CSV data into a React application using D3 utilities. It fetches a dataset of CSS named colors via `d3.csv` and stores the parsed result in React state with `useState` and `useEffect`. The view displays a concise summary of the loaded data—its size in kilobytes, row count, and column count—using `d3.csvFormat` and a custom `message` module. The page includes React 16.13.1 and D3 v6.6.0 from CDNs, and renders a loading message until the asynchronous data request completes.
