{"version":"1.0","type":"rich","title":"Smiley face D3.js","description":"A yellow smiley face, composed of SVG circles and a path-based mouth, demonstrates D3.js DOM selection and manipulation. The code uses the `select` and `arc` APIs from D3 v5 to construct the face, and its appended groups and shapes are animated via chained `transition().duration(2000)` calls, which move the eyebrow rectangles up and down. The animation runs over a 960x500 SVG canvas, using a static JavaScript bundle for rendering.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/4feb34a399a640abab4983a761497b2c?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
