Smiley Face Part 1
This example displays a static smiley face rendered as a yellow circle with two black eyes, created using React and SVG elements. The code defines circle components with explicit attributes for positioning, radius, fill, and stroke, a minimal approach before adding the mouth in later parts. It uses React’s `ReactDOM.render` to mount the SVG into the page, with the face centered on a fixed 960×500 canvas. The visualization demonstrates basic SVG composition within a React component structure.
