{"version":"1.0","type":"rich","title":"Let's make a face with D3.js!","description":"A yellow smiley face with animated eyebrows demonstrates D3.js DOM manipulation and SVG rendering. The code uses `d3.select` and `d3.append` to construct circles, rectangles, and a mouth path via `d3.arc`. Chained `transition().duration()` calls repeatedly shift the eyebrow group’s `transform` attribute, creating a bouncing motion. All elements are centered within a fixed 960×500 SVG viewport.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/09c9fd2057884f67a83476a8a7996f15?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
