This example renders a stylized smiley face using SVG elements composed through React components, with the D3 arc generator defining its mouth, eyebrows, and ears. The face features pink circular head with layered eyes, a black nose, a red tongue, and curved arcs for brows and lips. Built with React 16.9 and D3 v7, the code uses d3.arc() to create path geometries and React’s declarative JSX to position elements within an SVG canvas, offering a playful demonstration of combining D3’s geometric utilities with React’s component-based rendering.
