This fork of the Cat smiley example renders a stylized feline face as a static SVG using React and D3 v7. The code defines geometric primitives—circles for the eyes, an ellipses, lines for whiskers, and arc generators for the mouth, eye highlights, and ears—composed within an SVG group centered on the canvas. D3’s `arc()` API constructs the curved mouth and ear paths, while React handles the declarative JSX structure. The visualization demonstrates a purely illustrative use of D3 shape generators rather than data mapping, with colors and stroke widths fixed in the code.
