This visualization demonstrates a minimal React and D3 integration that loads a CSV dataset of CSS named colors and displays its summary statistics. The app fetches the data using D3’s `csv` function within a React effect hook, then uses React state to manage the loaded data. Once fetched, the code formats a message with `d3.csvFormat` to report the file size in kilobytes, row count, and column count. During loading, the interface shows a “Loading...” message, and the final output is rendered as large monospace text using React’s `useState` and `useEffect` hooks.
