{"version":"1.0","type":"rich","title":"Fork of Smiley Face Part IV","description":"This example renders a smiley face as an SVG using React components and D3’s `arc` API. A yellow circle with a black stroke forms the head, while two black circles serve as eyes and a D3-generated path creates the mouth. The code defines a `BackgroundCircle` React component and uses `ReactDOM.render` to mount the visualization, with all dimensions and positions computed as constants. The face is centered on a 960×500 canvas, and the mouth arc uses specified inner and outer radii with angular start and end points.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/deca398e29e7485da93c21c1138b1e77?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
