The example constructs a cartoon face from simple geometric shapes using D3.js v5 and SVG rendering. It employs `d3.select` to append circles and paths directly to an SVG container, with `d3.scaleOrdinal` mapping color values for facial features. The face is composed entirely of static elements—no animation or interaction—and the code relies on basic D3 utilities like `d3.arc` for the mouth shape. Styling is handled via an external stylesheet that resets margins and hides overflow. The visual result demonstrates how D3's declarative DOM manipulation can build complex illustrations from primitive SVG components.
