This example shows a stylized smiley face rendered as a static SVG graphic, composed of a yellow background circle, two eyes, and a curved mouth. The face is centered on a 960 by 500 canvas using a React component tree that composes reusable subcomponents for each facial feature. The code leverages React 17 and D3 v7, specifically using the `arc()` generator from the `d3` module to create the mouth’s path. All shapes are drawn with SVG circles and paths, with positions and sizes defined by constants passed as props.
