A stylized face, composed of geometric shapes in SVG, is drawn on a bright yellow circular background. The face features two circular eyes and rectangular eyebrows, which shift upward and downward in a looping animation using D3 transitions. A smiling mouth is rendered as a partial arc using the `d3.arc` API to generate the path data. The D3 code builds the entire composition programmatically, positioning elements relative to the canvas center and animating the eyebrow group’s transform attribute over time.
