This example shows a simple smiley face rendered with three circles: a large yellow head and two smaller black eyes. The SVG is drawn with fixed coordinates and hardcoded stroke and fill values, using React and JSX for markup. The code directly places a 960x500 SVG element, positioning the face and eyes with absolute pixel values, and sets the body margin to zero to hide overflow. It is a minimal, static visualization that demonstrates basic SVG circle rendering without any interactive or animated behavior.
