{"version":"1.0","type":"rich","title":"face","description":"A smiley face drawn with D3.js animates its eyebrows up and down in a looping transition. The SVG face uses a yellow circle, two eye circles, and an arc-generated mouth, while the eyebrows are rectangles that move via chained `transition.attr` calls over two-second intervals. D3 v5’s `select` and `arc` APIs build the static elements, with the animation driven by D3’s transition system.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/96fc356b3a74458c86b4bbd2f2eaef4f?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
