A yellow circle face with black-outlined features is built from SVG shapes using D3 selections. The code creates concentric facial elements—two circles for eyes, two rectangles for eyebrows, and an arc-generated mouth—positioned via translation transforms. The eyebrows animate through chained `transition().duration()` calls that move them vertically down and back up over two seconds each. The example demonstrates how D3 v5’s `arc` generator and SVG group elements compose a stylized character from primitive shapes.
