Fork of Smiley Face Part IV
This fork of Smiley Face Part IV renders a cartoon smiley face with decorative elements—including a hat, ears, eyebrows, and a nose—using React and D3 v7. The face is built from SVG shapes: circles for the eyes, `d3.arc()` paths for the mouth and ear arcs, and lines for the eyebrows. All components are positioned within an SVG coordinate system centered on the face, with React managing the component structure and D3 generating the arc geometries. The code uses D3’s `arc()` API for curved shapes and React’s `ReactDOM.render` to mount the visualization.
