A React starter template renders the text “Hello React” in a blank browser window. The example demonstrates the minimal setup required to integrate React with a visualization gallery, using `ReactDOM.render` to mount a functional component into a `#root` div. It loads React 16.9.0 and ReactDOM from CDN links in `index.html`, with the main logic contained in `index.js`. The code shows no data or interactive behavior, serving solely as a foundation for building React-based examples within the gallery.
