A cheerful, schematic face is built from SVG primitives in a 960×500 viewport, centered via a translated group. Its yellow head, black-outlined circle, two dark eyes, and a wide mouth arc are composed with D3’s `select`, `append`, and `arc` APIs. The eyebrows, drawn as rectangles, animate upward and back down over two seconds using chained `transition().duration(2000)` calls on the group’s `transform` attribute, while the rest remains static.
