This example uses React and D3 v7 to render a cat-themed smiley face as an SVG. The code constructs the face from basic shapes: a pink circle for the head with a purple border, red eyes with white highlights, an orange ellipse nose, and a black mouth drawn using D3’s `arc` generator. Additional D3 `arc` paths create white eye crescents and purple ears, while colored lines suggest whiskers. All elements are positioned with explicit coordinates and transforms, with no external data source, purely illustrating geometric composition and D3 arc-based path generation.
