This example shows a stylized smiley face built from modular React components, with a yellow circular background, two eyes, and an arched mouth rendered as SVG elements. Derived from the “Let’s Make a Face” tutorial, it uses fixed geometric prop values for positioning and sizing. The code leverages React 18 for component composition and the d3.arc API from d3.v7 to generate the mouth path, all within a simple SVG container that translates the face to the center of the viewport.
