A face built from basic geometric shapes appears on a yellow circular head with two black eyes, created entirely with D3.js v5 SVG elements. The code uses `d3.select` to append circles for the head and eyes, while the mouth is drawn with the `d3.arc` shape generator using an inner and outer radius with specified start and end angles. All elements are positioned relative to the SVG's width and height, demonstrating simple compositing of primitive shapes in a static visualization.
