{"version":"1.0","type":"rich","title":"Let's make a face with D3.js!","description":"A D3.js animation demonstrates basic DOM manipulation by constructing a smiley face from SVG primitives. The face consists of yellow circles for the head and eyes, rectangular eyebrows, and a path-based mouth generated with the `d3.arc` shape. Using chained `transition` calls, the eyebrows animate downward and back over two-second intervals. The code imports `select` and `arc` from D3, appends elements to an SVG canvas, and applies coordinate transforms to position facial features relative to the center.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/15918882c6d74d37b394bf8e73902317?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
