This example shows a yellow smiley face rendered as an SVG graphic, featuring two black eyes and a wide elliptical mouth against a plain background. The face is constructed using React components that generate SVG elements, with the circle shape for the head and eyes, and an ellipse for the mouth. The code imports the `arc` function from D3 v7 to define the mouth’s path, though the actual arc is commented out in favor of the ellipse. The drawing is centered within a fixed 960 by 500 pixel viewport, with positions calculated using constants for offsets and radii.
