This example demonstrates a minimal React application that fetches a CSV file containing CSS named colors using d3.csv and displays the first parsed data object to the console. The app uses React hooks, including useState and useEffect, to manage loading state and trigger the data request. A plain HTML document loads React, ReactDOM, and d3.v3 from CDNs, while the main component renders a "Loading..." message until the asynchronous data arrives. Although no visualization is rendered, the example illustrates the basic pattern for integrating D3 data loading within a React component.
