This example demonstrates how to load and display a CSV dataset within a React application using D3.js. The interface initially shows a "Loading..." message, then presents the fetched data in a formatted table using `d3.csvFormat`. The data is retrieved asynchronously from a GitHub gist containing CSS named colors. The implementation relies on React's `useState` and `useEffect` hooks to manage the data state and trigger the fetch operation exactly once, using `d3.csv` to parse the remote CSV file.
