This example shows a stylized, animated face built as an SVG graphic. A yellow circle forms the head, with black circles for eyes, rectangular eyebrows, a nose, and an arc-based mouth. The right eyebrow repeatedly moves up and down using chained `transition.attr` calls. The visualization is constructed with D3 v6 selection methods and the `arc` generator, drawing all shapes in a coordinate system centered via an SVG group transform.
