This example demonstrates how to load external data into a React application using D3 utilities. It fetches a CSV file containing named CSS colors from a GitHub gist, then displays summary statistics about the dataset, including the number of rows, columns, and file size in kilobytes. The code uses `d3.csv` to parse the remote CSV, `d3.csvFormat` to calculate its size, and React’s `root` DOM element to render the output via plain text. D3 v7 and React are integrated without additional state management.
