This example builds a simple cartoon face from SVG shapes using D3.js v5, including circles for the eyes, rectangles for eyebrows, and a path generated with d3.arc for the mouth. The face is centered on a yellow circle, and the eyebrows animate vertically using chained transition.attr calls with a two-second duration each. The code selects the SVG element directly and applies transforms to group elements, demonstrating basic shape creation, layout, and animation in a declarative D3 workflow.
