This example demonstrates how to load external data in a React application using D3 utilities, displaying a summary of the dataset’s size, row count, and column count. The visualization fetches a CSV file of CSS named colors via `d3.csv` and manages the asynchronous result with React’s `useState` and `useEffect` hooks. Once loaded, the data is formatted using `d3.csvFormat` to compute its size in kilobytes, while React renders the resulting text statistics as SVG content.
