This example shows a simple smiley face built from three SVG circles: a large yellow face with a black stroke, plus two smaller eyes. The SVG is rendered directly in the browser with a fixed 960 by 500 viewport. The code uses plain SVG elements (`circle`) and CSS to style the body with no margin, making the face fill the entire viewport. No external libraries are used; the drawing relies solely on hardcoded coordinates and stroke properties. The face is static, with no animation or interaction, serving as a minimal demonstration of vector-based drawing.
