{"version":"1.0","type":"rich","title":"Creating a scene","description":"The example shows an animated smiley face created with D3.js, where the eyebrows move up and down in a looping motion. The face is built using SVG shapes, including circles for the eyes and an arc for the mouth, all centered within an SVG canvas. The code uses D3’s `select` and `arc` functions, along with chained `transition().duration()` calls to animate the eyebrow positions. A separate HTML scene displays a natural landscape with CSS-animated animals, including a cat, dog, bird, and butterfly, each moving via keyframes. The rendering relies on static image assets for the animals and flowers, while the D3 portion handles the dynamic facial animation.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/d6ddab20cdd84bceb3f5f38c2e962449?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
