A yellow smiley face rendered as SVG in a React component, with two black eyes and a circular mouth created using a D3 arc path generator. The face circle is centered with a black stroke, while the eyes and mouth are positioned relative to the center using hardcoded offsets and radii via the `d3.arc()` API. The entire SVG is drawn inside a `<g>` transform translation, and the code uses React 17 and D3 v6 to compose the static visualization.
