This example renders a stylized cartoon face using React and D3 v6, with all elements drawn in SVG. The face features sky-blue circular cheeks, white-outlined eyes with yellow irises and white pupils, angled rectangular eyebrows, a polygonal hair shape, a nose, a smile arc, and an ear line. The code computes positions relative to the window dimensions and uses D3’s `arc()` generator for the mouth path. Component state is managed with React, while D3 handles the geometric calculations for the facial features.
