Smiley Face
A yellow Smiley Face is rendered as an SVG using React. The face consists of a large yellow circle with a black stroke, two black eyes, and a mouth drawn as an arc. The visualization uses React components to structure the SVG elements and the D3 `arc` function to generate the mouth's path. The code defines reusable components and calculates the face's geometry from fixed constants for the center, radius, and offsets.
