{"version":"1.0","type":"rich","title":"Let's make a face with D3.js!","description":"An animated smiley face is built from basic SVG shapes, with eyes that blink and eyebrows that raise and lower in a looping transition. The example demonstrates fundamental D3.js DOM manipulation by selecting the SVG canvas, appending a group, and positioning circles, rectangles, and a path for the mouth. Using chained `transition()` calls, the code animates the eyebrow’s transform attribute and the eye’s radius over two-second durations. The mouth is drawn with D3’s `arc` generator, and all elements are centered via SVG group transforms.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/d4e37852957d481c9ef7a5dc1cedfdcb?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
