Smiley Face
This example uses React and SVG to render a static smiley face. The face is drawn with three SVG circle elements on a 960x500 canvas: a yellow outer circle for the head and two black circles for the eyes, all with visible black strokes. The React component renders only a heading, while the SVG markup is placed directly in the HTML body, so the visualization is not generated through React itself. The code relies on the React and ReactDOM production libraries and a bundled JavaScript file, though no interactive behavior is implemented.
