This example demonstrates how to combine D3 utilities with React’s state management. It loads a CSV dataset of CSS named colors using D3’s `csv` function, then displays a message showing the data’s size in kilobytes, row count, and column count. React’s `useState` and `useEffect` hooks manage the asynchronous data loading, while conditional rendering shows a loading state until the data arrives. The visualization is minimal—a single heading—but effectively illustrates the integration pattern.
