A yellow circle with two eyes, eyebrows, and a mouth forms a simple face in an SVG canvas. The code uses D3 v5 selections to build the shapes, with `d3.arc` generating the mouth’s path. A `transition` applies a two-second upward and downward movement to the eyebrow group, animating the face without any data input. All elements are centered via a translated `<g>` group, and the rendering relies strictly on SVG attributes and D3’s transition system.
