{"version":"1.0","type":"rich","title":"Refactor React - Smiley Face","description":"A React component renders a yellow smiley face as a scalable vector graphic, composed of a circular background, two eyes, and a smiling mouth. The face is built from separate functional components—`BackgroundCircle`, `Eyes`, `Mouth`, and `FaceContainer`—that accept numeric props for dimensions and positioning. The mouth uses the `d3.arc` generator from d3.v6 to create a semicircular path, while all elements are centered within an SVG container via a translation transform. The example demonstrates how to structure reusable, data-driven visual components with React and D3.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/5d4c13c2c1834b1c8370c5da67963cf5?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
