EXAMPLE FOR HAPPY FACE Part 1
A simple SVG drawing depicts a happy face, composed of a large yellow circle with a black stroke as the head, and two smaller black circles as eyes. The code creates the shapes using raw `<circle>` elements within an SVG container, positioning them with explicit `cx` and `cy` attributes. The page is styled to remove margins and hide overflow. The visualization serves as a basic, static example of geometric shape composition without any interactive or data-driven elements.
