{"version":"1.0","type":"rich","title":"Smiley Face","description":"A yellow smiley face rendered with React and D3.js uses SVG circles for the head and eyes, and a D3 arc path for the mouth. The `d3.arc()` API defines the mouth’s inner and outer radii, with start and end angles creating a curved smile. Stroke width and offsets position the facial features relative to the canvas center. The static composition relies on hard-coded dimensions and D3’s arc generator, with no interaction or animation.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/48564b4f196d491b99ee48eb55488f50?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
