This example demonstrates a minimal setup for using React to render a single, large text message. It displays "Hello World" as static text, centered on the page. The application is built using the React and ReactDOM libraries, which handle the component rendering and DOM updates. All the styling, including the font size and text alignment, is applied through CSS. The React components are compiled into a `bundle.js` file, which is loaded by the browser to render the message dynamically. The example highlights the basic structure of a React application without any interactive or data-driven features.
