This example demonstrates how to load and handle a CSV file using D3’s `d3.csv` method within a React application. The code fetches nutritional profile data from a GitHub Gist and processes the resulting promise chain, logging the text content of the response. It imports React and ReactDOM to set up rendering, though the actual UI is minimal. The example highlights asynchronous data loading with `Promise.resolve` and `.then` callbacks, bridging D3’s CSV parsing with React’s component lifecycle, while relying on D3 v5 and React 16.10.
