{"version":"1.0","type":"rich","title":"Smiley d3","description":"A yellow smiley face rendered as an SVG reacts to a repeating two-second animation cycle: its eyebrows shift downward and then reset, creating a winking effect. The face is composed of geometric primitives—circles for the head and eyes, rectangles for the brows, and a path for the mouth drawn with d3.arc. The code uses d3's selection API and transition system, running within VizHub's d3.v5 environment.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/12eeb125d18f4b9fb8a260e1edff7358?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
