{"version":"1.0","type":"rich","title":"Let's make a face with D3.js!","description":"A smiley face built with D3.js demonstrates core DOM manipulation through SVG elements, including circles for the eyes, rectangles for eyebrows, and an arc-generated mouth. Animated transitions move the eyebrows upward and back down over two-second intervals, showing how `transition().duration()` sequences chained animations. The face is centered using SVG group transforms, while D3 v5’s `select` and `arc` APIs handle element selection and path generation. The example highlights fundamental D3 concepts like attribute setting, coordinate positioning, and timed state changes within a static SVG canvas.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/30545496468a4b3c938947e878b83a9d?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
