This example demonstrates how to load CSV data into a React application using D3 utilities. It displays a summary of the CSS named colors dataset, showing file size in kilobytes, row count, and column count as large text. The code uses the `useState` and `useEffect` hooks from React to manage the loading state, while D3’s `csv` function fetches and parses the data from a GitHub gist URL. The `message` function formats the statistics using `d3.csvFormat` to calculate the data size.
