This example displays a text summary of a loaded dataset, showing the file size in kilobytes, row count, and column count. It demonstrates how React state manages asynchronous data loading, using the `useState` and `useEffect` hooks to fetch and store the data. The code uses d3's `csv` function to parse a remote CSV file containing CSS named colors, and ReactDOM renders the resulting message. Before the data arrives, the interface shows a "data is loading..." message.
