This example shows a simple yellow smiley face rendered as an SVG graphic centered on a 960 by 500 canvas. The face consists of a yellow circle with a black outline, two black eye circles, and a black mouth arc. The drawing uses React for declarative SVG construction, while D3’s `arc()` function generates the path data for the mouth. The code constructs the shape with hardcoded dimensions for the face, eyes, and mouth, all positioned relative to the canvas center. The rendering relies on ReactDOM to mount the SVG onto the page’s root element.
