This example shows a stylized smiley face built from three reusable SVG components: a yellow background circle, a pair of eyes, and a mouth drawn as an arc. The face is positioned at the center of a 1060×500 SVG canvas using React components that receive geometry props for radii and offsets. The mouth path is generated with d3.arc(), while BackgroundCircle and Eyes render plain SVG circle elements. React 16.9 and D3 v7 work together, with all drawing handled declaratively through JSX.
