This example displays summary statistics for a dataset of CSS named colors, showing the file size in kilobytes, row count, and column count as large text. It loads the data from a GitHub gist using `d3.csv`, stores it in React state with the `useState` and `useEffect` hooks, and renders the result via ReactDOM. The implementation combines D3's `csvFormat` utility for calculating data size with React's component lifecycle for managing asynchronous data loading.
