A fork of the Smiley Face Part III builds a classic smiley face using React and D3 in a single SVG. The code renders a yellow circle for the head, two black eye circles, and a mouth arc created with D3’s `arc()` generator, all positioned via a central transform. React functional components handle the SVG structure, while D3’s arc API computes the mouth path with specified angles and radii. The static visualization uses fixed dimensions (960×500) and hard-coded coordinates for all facial features, with no interactive or animated behavior present.
