This example draws a yellow smiley face as a static SVG graphic using React and D3. It shows a circular face with two black eyes and a curved mouth, centered within a 960×500 viewport. The code uses React to render SVG elements, and the D3 `arc` function generates the mouth path from specified inner and outer radii and angular ranges. All shapes are positioned relative to the center using a transform group, with hardcoded offsets and stroke widths.
