Smiley Face Part I
A yellow smiley face rendered with SVG in React, drawn programmatically using D3's arc generator. The code sets explicit pixel coordinates for the circle background, two black eye circles, and a mouth path created with d3.arc, using inner and outer radii plus start and end angles. The face is centered on a 960 by 500 canvas, with a black stroke surrounding the yellow circle, and all shapes are positioned relative to a translated group.
