This example shows a classic smiley face rendered as an SVG graphic. A large yellow circle with a black outline forms the head, while two smaller filled circles serve as eyes and an arc-shaped path creates the smile. The visualization uses React to define the component structure and d3’s `arc` generator to compute the mouth’s path based on specified inner and outer radii and start/end angles. The face is centered within a fixed 960 by 500 viewport using SVG transforms and circle elements.
