This example demonstrates how to load and summarize CSS named colors data within a React application using D3 utilities. It displays a text summary showing the dataset size in kilobytes, row count, and column count, with a "Loading..." placeholder before the data arrives. The code uses React’s `useState` and `useEffect` hooks to manage async state, and D3’s `csv` function to fetch the remote CSV file, while `d3.csvFormat` computes the summary metrics.
