This example displays a simple React application that renders a static heading. It uses React and ReactDOM to mount a single functional component, which outputs an `<h1>` element with the text “hii” into the DOM root. The code relies on React’s `ReactDOM.render` method to insert the component into the page, with the styling defined in the HTML’s CSS. No animation or data visualization is present; the example serves as a minimal starter template for a React-based project.
