A smiling face is drawn with SVG primitives, centered on a yellow circle with black outlines, including eyes, eyebrows, and a mouth. The example demonstrates basic D3 v5 shape generation and selection, using `d3.select` to manipulate SVG elements and `d3.arc` to create the mouth path. All elements are positioned relative to a central group, with geometric constants for spacing and offsets. The static visualization is built entirely in code, with no external data source.
