A yellow circular face with black eyes, eyebrows, and a mouth is drawn using D3.js v5. The code builds SVG elements directly, positioning a central circle, two eye circles, and eyebrow rectangles with a path for the mouth created via `d3.arc`. The eyebrows animate using chained `transition` calls over two seconds each, moving downward and returning upward. All geometry relies on computed spacing and offset constants, with the SVG centered via a `transform` attribute.
