This fork of Smiley Face Part II renders a classic smiley face as a React component, with a yellow circle, black outline, and two eyes, all scaled to fill the browser window. The code builds the SVG using React elements and the D3 `arc` function, though the mouth is not drawn. It uses fixed pixel offsets for eye placement and computes the face radius from the viewport height. The visualization demonstrates a simple hybrid of React for DOM rendering and D3 for SVG geometry, updating to any window size.
