This example demonstrates the use of D3 utilities and React state to load and summarize a dataset of CSS named colors. It shows both a loading message and a three-line summary of the data: size in kilobytes, number of rows, and number of columns. The code uses React's `useState`, `useEffect`, and `d3.csv` to fetch the remote CSV file, then formats it with `d3.csvFormat` within a custom `message` function. The React application renders the text output inside a `<pre>` element.
