An animated face drawn with SVG shapes is rendered inside a 960×500 viewport. The code uses D3 v5’s selection and arc helpers to construct the circular head, eyes, and a mouth path, while CSS handles the page layout. Eyebrow rectangles animate upward and downward through a chained `transition` call lasting two seconds per movement. The face is centered with a transform, and all elements rely on SVG attributes for positioning and styling.
