This example shows a simple smiley face built from three SVG circles: a large yellow head with a black stroke and two smaller black eyes. The code uses hardcoded SVG elements within an HTML document, setting explicit pixel coordinates for each circle’s center and radius. The rendering relies on standard SVG attributes like `cx`, `cy`, `r`, `fill`, and `stroke`, with no JavaScript libraries or data sources involved. The face is centered on a 960-by-500 canvas, and the page’s CSS hides any overflow for a clean presentation.
