{"version":"1.0","type":"rich","title":"Looping Transitions Example","description":"This example animates a simple face, including an elliptical head, eyes, pupils, eyebrows, and a mouth, with the eyebrows looping up and down in a continuous cycle. The loop is achieved by chaining two D3 transitions—one moving the eyebrow group down, the next moving it up—and invoking the same function again in the `transition.on(\"end\")` callback. The SVG is rendered using D3 v5, with shapes drawn via `.append()` for ellipses, circles, polylines, and an arc, and all positioning handled through `transform` attributes.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/c16c636a99ef478a91f9a67391ddba1d?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
