This example demonstrates how to build a simple cartoon face using basic SVG shapes and D3.js v5. The code creates a yellow circle for the face, two circles for eyes, rectangles for eyebrows, and a semi-circular arc for the mouth, all positioned within a centered group. It uses D3’s `select` to manipulate the SVG, the `arc` generator from the `d3-shape` module to define the mouth path, and inline attribute chaining to set coordinates and styling. The face is assembled procedurally with hardcoded offsets and dimensions, illustrating fundamental SVG construction with D3.
