This example demonstrates a React component that asynchronously loads a CSV file of CSS named colors via D3’s `csv` utility, then displays a summary of the dataset using React’s `useState` and `useEffect` hooks. While the data is fetching, the interface shows a “Loading...” message. Once loaded, it renders a text summary reporting the file size in kilobytes, row count, and column count. The code uses `d3.csvFormat` to calculate the byte size and relies on React’s state management to update the view.
