This example displays metadata about CSS named colors—file size, row count, and column count—in large text. It loads a CSV dataset from a GitHub gist using D3’s `csv` utility, then stores the parsed data in React state via the `useState` and `useEffect` hooks. After fetching, a custom message function formats the statistics for display. The rendering relies on React 17 and D3 v6, with the data source defined as a raw URL. While loading, the text shows “Loading …” until the asynchronous fetch completes.
