A simple SVG drawing depicts a smiling face as a large yellow circle with a black stroke, containing two smaller black circles as eyes. The face is centered on a white background within a 960 by 500 pixel viewport. The example uses raw SVG elements—`circle` tags with attributes for center coordinates, radius, fill, and stroke—embedded directly in an HTML page with CSS to remove page margins and hide overflow. No JavaScript libraries or data sources are involved; the visualization is purely static markup.
