This example shows a stylized face built from SVG primitives, rendered through React's declarative component model. A yellow background circle with a black stroke holds two eye circles and a mouth arc, all positioned relative to a central transform. The code uses d3.arc to compute the mouth path, while React handles the component structure and D3 v7 provides the arc generator. The face is centered using D3’s coordinate translation, with dimensions and offsets defined as constants.
