A smiley face is drawn as an SVG graphic centered on a 960x500 canvas. The face features a circular head, two eyes with green pupils, a purple nose, and a curved mouth, all rendered with black strokes and thick line segments for eyebrows and hair. The visualization uses React for rendering and d3.arc to create the mouth path. All shapes are positioned with absolute coordinates, and the code relies on d3.v7 and React 17 to produce the static vector illustration.
