This example demonstrates a React application that loads a CSV dataset and displays a message about the number of rows it contains. The application uses the `d3.csv` API to fetch data from a remote gist URL, and the React `useState` hook to manage the loading state. A large, centered message shows either "Still Loading" while data is being fetched, or the row count once the CSV is parsed. The visualization is minimal, focusing on the data-loading workflow rather than graphical rendering, with a large 13em font size for the text output.
