This example draws a minimalist smiley face from geometric primitives in an SVG rendered with React. A yellow circle forms the head, two smaller circles serve as eyes, and a mouth is created using D3’s `arc()` path generator with inner and outer radii. The code uses React for component rendering, D3 v7 for the arc path, and positions elements around a central translation from absolute SVG coordinates. The face is static, with no interaction or animation.
