This example renders a static React application titled “smiley face Part 1,” which displays a single “Hello jsx” heading. The code uses React 18 and ReactDOM to mount a simple component onto the DOM, while Babel Standalone processes the JSX in the browser. The HTML page includes an embedded YouTube video that likely serves as tutorial content, and the styling sets a full-bleed layout with hidden overflow. The visualization itself is minimal, demonstrating the integration of React with un-prefixed ReactDOM rendering rather than any data-driven graphics.
