This example shows a simple yellow circle with two black eyes, forming a basic smiley face on a blank white background. The SVG drawing uses two overlapping circle elements for the face and eyes, all rendered with explicit stroke and fill attributes. The code defines three separate `<circle>` tags inside a fixed 960×500 SVG viewport, with the body’s CSS removing margins and hiding overflow. No JavaScript libraries are used; the visualization relies entirely on plain HTML and SVG markup.
