This example shows a stylized, half-completed smiley face composed of SVG shapes, including a gradient-filled background circle, elliptical eyes, a mouth drawn with a d3 arc path, and teeth made from a mix of arc and line elements. The React code structures the face using separate components like Face, Eyes, and Mouth, while leveraging the d3 arc() API to generate the mouth’s curved path. The layout is positioned within an SVG container using transforms, with fixed dimensions and coordinates that center the face on a 960 by 500 canvas.
