This example shows a simple smiley face built from three SVG circles: a large yellow head with a black outline and two smaller black eyes. The face is statically positioned at the center of a 960 by 500 pixel canvas. The visualization is created manually using raw SVG elements—`<circle>` tags—plus inline CSS to remove page margins and hide overflow. No JavaScript libraries or data sources are involved; the rendering relies entirely on the browser’s native SVG support.
