This example demonstrates loading and parsing a CSV file containing CSS named colors, then displaying summary statistics about the dataset. Using React hooks (useState and useEffect) alongside d3.csv, it fetches data from a GitHub gist URL and presents the file size in kilobytes, row count, and column count. The application integrates D3 v5 for CSV parsing and formatting within a React 16.9 component, showing a loading state while data is being fetched.
