This example demonstrates a minimal workflow for loading and summarizing external data within a React application. It uses the D3 utility `csv` to fetch a remote CSS Named Colors dataset, and React's `useState` and `useEffect` hooks to manage the asynchronous loading process. After retrieval, it displays a text summary generated by a custom `message` function, which reports the data's size in kilobytes, the number of rows, and the number of columns. The visualization itself is a plain text readout, with the loading state showing "loading" until the data arrives.
