A yellow smiley face is drawn with SVG circles for the head and eyes, and a D3 arc path for the mouth. The code uses React to render the SVG elements and d3.arc to compute the mouth’s curved shape, with explicit angle ranges and inner/outer radii. The face is centered using a translated group, and the head and eyes are styled with fixed stroke widths and radii. The visualization is purely a static geometric composition, with no interaction or data-driven updates.
