A stylized smiley face is drawn as a set of SVG shapes, with a gradient-filled background circle, two asymmetric eyes, a mouth arc, and a row of teeth rendered as lines. Built with React and D3 v7, the face’s geometry is parameterized as props, and D3’s `arc` generator creates the mouth and teeth paths. The teeth use hard-coded coordinate offsets to simulate individual tooth separations, while the SVG is assembled from reusable component functions with a linear gradient defined in `defs`.
