A yellow smiley face is drawn centered in an SVG canvas, with black eyes and a curved mouth, all constructed from React components. The visualization uses D3’s `arc` generator to create the mouth’s path, while the face, eyes, and stroke are simple SVG circles. The entire face group is rotated 180 degrees to orient the smile upward, and the layout is fixed at 960 by 500 pixels with reusable React components for the background, eyes, and mouth.
