This example displays a simple yellow circle with black, fixed-position circles for eyes, drawn directly on an SVG canvas. The code uses raw SVG elements (`<svg>`, `<circle>`) with inline attributes for coordinates, fill, stroke, and dimensions; no JavaScript libraries or data sources are involved. The rendering relies solely on static SVG markup within an HTML page, producing a minimal smiley-face graphic. The viewport is set to overflow hidden, and the body margin is removed to frame the illustration cleanly.
