Smiley face
This example renders a simple smiley face using SVG circles: a large yellow circle for the face and two smaller black circles for eyes, all positioned on an empty 970 by 500 canvas. The drawing is defined directly in the markup with absolute coordinates and styling for fill, stroke, and stroke width. The page loads the React UMD build from a CDN, though the visualization itself relies solely on static SVG elements and does not employ any interactive behavior or dynamic data.
