This React starter example renders the text “Hello React” directly into a web page. It uses the React and ReactDOM libraries, specifically the `ReactDOM.render` method, to mount a simple functional component into a `div` with the id `root`. The page loads React and ReactDOM from unruly `unpkg` CDN scripts and relies on a separate `bundle.js` file to contain the compiled JavaScript. The example demonstrates a minimal setup for building React-based data visualizations.
