This example shows a yellow smiley face rendered as an SVG circle with two smaller circles for eyes, computed from fixed dimensions rather than loaded data. The face is built using React 18, with JSX defining SVG elements inside the App component. The face’s geometry is calculated via constants for center coordinates, offsets, and radii, then rendered by ReactDOM into the DOM. The code uses no external visualization libraries, relying solely on React’s declarative SVG rendering to position the shapes.
