This example demonstrates loading a CSV dataset into a React application using D3’s `csv` function. The app fetches CSS named colors from a GitHub gist and displays a count of loaded rows once the data arrives. While fetching, it shows a loading message, then switches to a report of the dataset length. The implementation relies on React’s `useState` and `useEffect` hooks to manage the asynchronous request, and uses D3 v5 for CSV parsing. The rendering is minimal, using standard HTML components rather than SVG, with no visual data representation beyond the row count.
