A smiley face rendered as a static SVG chart in React, composed from reusable components for the circular yellow background, eyes, and mouth. The face is centered in a 900 by 450 viewport, using D3's `arc` generator to draw the mouth as a half-annulus. Parameters like eye offset, radius, stroke width, and mouth dimensions are passed as props to the `Face` component, allowing for easy customization of the facial geometry.
