{"version":"1.0","type":"rich","title":"Smiley Face Part IV","description":"This example shows a smiley face built with React and D3, composed of a yellow circle, two black eyes, and a mouth drawn as an arc. The SVG elements are positioned using calculated constants for center coordinates, eye offsets, and radii. The mouth uses `d3.arc()` with specified inner and outer radii and start and end angles, rendered as a path. React renders the SVG structure, while D3 provides the arc generator. The face is centered within a 960×500 viewport, with a stroke applied to the outer circle.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/6e0453c22bcd40a39123ab06aa8361c5?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
