A face rendered as a yellow SVG circle on a black outline, with two fixed black eyes and a mouth drawn as a thick arc, is centered on a 960 by 500 canvas. The example demonstrates basic D3 shape construction in a React component, using the D3 `arc` function to create the smile and manual SVG `<circle>` elements for the face and eyes. The drawing is produced with declarative SVG attributes and D3’s arc path generator, showing how geometry can be composed in a browser-based visualization.
