This example assembles a friendly face from basic geometric shapes—circles form the eyes, and arcs create the smile—rendered as SVG elements on a 960×500 canvas. The page loads d3.v5 from a CDN and uses standard d3 selections and shape generators to position each facial feature relative to the center of the viewport. No data or interaction is involved; the face is static, with the code simply demonstrating how d3’s coordinate system and SVG primitives combine to construct a recognizable illustration.
