This example displays the message “Hello React!” centered on a blank page. The code uses React and ReactDOM to render a single component, `App`, which outputs the text within a styled `<div>`. The application is launched through a basic HTML structure that loads the React libraries from a CDN and includes a `bundle.js` file generated from the `index.js` source. The visualization relies solely on React’s component-based rendering, without any additional data sources or charting libraries.
