{"version":"1.0","type":"rich","title":"Test Let's make a face with D3.js!","description":"A smiling face rendered as yellow SVG circles, rects, and an arc path demonstrates fundamental D3.js DOM manipulation. Eyebrows animate upward and back down through chained `transition().duration(2000)` calls on the group’s `transform` attribute, while the mouth uses `d3.arc`. The code builds the figure by selecting the SVG, appending groups, and setting shape attributes for eyes, eyebrows, and face from fixed numeric constants, with no external data source.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/ce973cf3e12e497cae8b3ea3689883bb?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
