This example demonstrates how to load and summarize CSV data within a React application using D3 utilities. The interface displays a simple text report showing the data’s file size in kilobytes, row count, and column count. The code relies on React’s `useState` and `useEffect` hooks to manage the loading state, alongside D3’s `d3.csv` to fetch the remote dataset. The concise output is generated through a custom `d3.csvFormat` call within a helper module.
