{"version":"1.0","type":"rich","title":"Untitled","description":"A yellow smiley face with black-outlined eyes and a wide open mouth is rendered in D3.js. The animation moves the face’s rectangular eyebrows upward and back down in a looping transition. The code uses D3’s `select`, `arc`, and `transition` APIs to construct the SVG shapes and animate the eyebrow group’s transform attribute over two sequential two-second durations. The visualization demonstrates fundamental DOM manipulation by building each facial feature from primitive SVG elements.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/afefbe02dec4471582b9e7126fdeae49?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
