A stylized smiley face rendered with React and SVG, drawn as a yellow circle with black outlines and two solid black eyes. The mouth is created as a half-circle arc using D3's `arc()` generator, with its inner and outer radii and start/end angles defined explicitly. All shapes are positioned relative to the SVG center, and the face is built declaratively in JSX within a React component. The example demonstrates combining D3’s geometry utilities with React’s component model for static vector graphics.
