This example demonstrates loading data with React and D3 by fetching a CSV of CSS named colors and displaying summary statistics as text. The React component uses the `useState`, `useEffect`, and `useCallback` hooks, while D3’s `csv` function retrieves the dataset from a GitHub gist URL. Once loaded, the data’s size in kilobytes, number of rows, and column count are computed using `d3.csvFormat` and rendered directly in a `<pre>` element. A loading message appears until the asynchronous fetch completes.
