D3 working
This example shows a simple smiley face rendered as scalable vector graphics (SVG) through React. The face is composed of three circles for the head and eyes, plus a D3 arc path for the mouth, all positioned using a central translation. The code uses React 17 to manage the component structure, while the d3.arc API from D3 v6 generates the mouth’s curved path. All shapes are drawn with hardcoded coordinates and SVG attributes, with no external data source.
