This example renders a stylized, half-finished smiley face using React with SVG. The face is composed of separate, parameterized components—a gradient-filled background circle, elliptical eyes, an arc-based mouth, and line-drawn teeth. The visualization is built with React components and uses D3’s `arc` generator to define the mouth and teeth paths. All elements are positioned programmatically via props, such as offsets, radii, and stroke widths, within a single SVG canvas.
