An animated SVG face with black skin, red eyes, eyebrows, and a red arc mouth sits centered on a dark background. D3 v6 and the `d3.arc` shape generator draw the mouth and arched eyebrows, while chained `transition` calls move each eyebrow upward and back down over two seconds for a blinking or surprised effect. The face’s eyes are simple circles positioned with fixed spacing, and all elements are grouped inside a centrally translated `<g>` element.
