This example demonstrates how to load external data into a React application using D3 utilities. It fetches a CSV file containing named colors from a GitHub gist via `d3.csv`, then stores the resulting promise data in React state with the `useState` hook. The app renders the raw data object to the screen rather than visualizing it, and the stripped-down SVG markup in `index.html` suggests a possible future plot. It uses React 16.9, D3 v6, and SVG rendering, with dynamic sizing based on `window.innerWidth` and `window.innerHeight`.
