A React and D3 v5 component assembles a stylized smiley face from individual SVG primitives. Separate modules define the background circle, eyes, mouth, and nose, which are composed within an SVG container using JSX. The mouth is generated with a d3 arc generator, while the face layout uses explicit coordinate and radius props like `centerX`, `eyeoffsetX`, and `mouthRadius`. The face is rendered with a yellow fill and black stroke, centered on a 360 by 360 canvas.
