This example uses React with D3 to render a stylized smiley face as an SVG graphic. The visualization constructs the face from primitive shapes—a yellow circle for the head, two dark circles for eyes, red cheek circles, and a mouth drawn as an arc path created with D3's `arc` generator. All elements are positioned relative to the center of a 960×500 canvas using SVG transformations, with stroke widths and radii defined as constants. The code demonstrates how D3's arc path generator integrates with React's declarative SVG rendering to produce a simple, vector-based illustration.
