This example demonstrates how to fetch and display a summary of a CSV dataset of CSS named colors. It uses React state to manage the loading lifecycle, initially showing a loading message, then reporting the dataset’s size in kilobytes, row count, and column count after the data arrives. The code employs the `d3.csv` function to load the data from a GitHub gist, `d3.csvFormat` to calculate its byte size, and React hooks (`useState` and `useEffect`) to handle asynchronous updates.
