A smiley face rendered as a yellow SVG circle with black outline, two eyes, and a smiling mouth, centered on a blank canvas. The visualization uses React components for each facial feature, with D3’s `arc` generator defining the mouth’s curved path. Hardcoded dimensions for eye offset and radius, mouth radius, and stroke width control the proportions. The scene is drawn entirely via SVG primitives within a single `<g>` transform, with no interactive or animated behavior.
