A yellow circle with a thick black outline dominates the SVG canvas, representing a smiling face with two smaller black circles as eyes. The example demonstrates a bare minimum HTML page embedding raw SVG elements directly in the markup. It uses the `<svg>` and `<circle>` SVG APIs, with no JavaScript libraries or external data sources, to render a simple static visualization. The page sets the body margin to zero and hides overflow to display the graphic edge-to-edge.
