{"version":"1.0","type":"rich","title":"ICE-4","description":"A green smiley face animates by moving its rectangular eyebrows up and down. The demo shows fundamental DOM manipulation with D3.js v5, using `d3.select` and `d3.append` to build SVG circles, rectangles, and paths. The eyebrows transition vertically via `transition().duration(2000)` chained calls. The mouth is drawn with the `d3.arc` generator. The animation runs continuously, shifting the eyebrows between two Y-offsets over two-second intervals.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/9a1659ca73e04ed3b38c1574f377e67c?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
