Fork of Smiley Face Part I
A smiley face rendered in SVG using React components for the background circle, eyes, and mouth. The code imports the D3 arc function to generate the mouth path, and uses React functional components with props for positioning. The visualization is centered within a 960x500 SVG canvas, with the face grouped and translated to the middle. The mouth is drawn as an arc spanning from 90 to 270 degrees, while the background circle has a yellow fill and black stroke.
