This example shows a stylized, smiling face composed of layered SVG shapes, including a gradient background circle, asymmetric eyes, an arc-based mouth, and a set of teeth drawn with lines. The code builds the face using React components and D3’s `arc` generator to define the curved mouth and tooth shapes. Custom props control dimensions, spacing, and stroke widths, while a linear gradient fill is applied to the background circle. The face is centered within a fixed 960 by 500 SVG canvas, with all elements positioned relative to that center point.
