This example displays a static yellow smiley face made of three SVG circles: a large head and two smaller eyes, positioned on a 960×500 canvas. The React framework renders a "Hello World" heading alongside the hardcoded SVG markup, which is drawn directly in the HTML using circle elements with explicit cx, cy, and r attributes. The visualization uses React 16.7 and SVG, with black strokes and a yellow fill, while the accompanying README notes it is halfway toward a more complete face.
