A yellow smiley face rendered in SVG, composed of a circular face, two black eyes, one red eye, and a thick red arc mouth. The visualization uses React for component structure and D3’s `arc` generator to compute the mouth path. All shapes are positioned via SVG transforms and coordinate offsets, with hardcoded constants for dimensions. The example demonstrates a simple, non-interactive static graphic built with D3 v5 and React 16.9.
