This example shows how to build a cartoon face using D3.js v5 SVG primitives, assembling circles for the head and eyes with rectangles for eyebrows and an arc-generated path for the mouth. The code positions these elements within a centered group using translate transformations, while the d3.arc API calculates the mouth’s curved shape based on specified inner and outer radii and angle ranges. All shapes derive their attributes from explicit numeric constants, demonstrating manual coordinate layout rather than data binding or scales.
