This example displays summary statistics about CSS named colors, loading the data from a CSV file hosted on GitHub. It shows the file size in kilobytes, the number of rows, and the number of columns as text in a large monospace font. The app uses React hooks (`useState`, `useEffect`) to manage asynchronous data loading, while D3’s `csv` function fetches and parses the dataset. A custom `message` function formats the statistics, and React renders the result or a “Loading…” placeholder.
