{"version":"1.0","type":"rich","title":"Hello VizHub","description":"A yellow smiley face rendered in SVG demonstrates basic D3 shapes and transitions. The code uses d3.select and d3.arc from D3 v5 to draw the head, eyes, eyebrows, and mouth, with d3.transition animating the eyebrows downward and back upward. The SVG canvas is 960 by 480 pixels, and all elements are positioned programmatically via translation transforms. A static dataset is not present; instead, hardcoded dimensions and angles define the geometry.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"","width":960,"height":500,"cache_age":3600}
