{"version":"1.0","type":"rich","title":"Let's make a face with D3.js!","description":"A smiley face rendered in SVG animates its eyebrows in a looping motion. The example demonstrates fundamental D3.js DOM manipulation by appending circles, rectangles, and a path to an SVG group, using `d3.arc` for the mouth. The eyebrows move via chained `transition().duration()` calls that shift their vertical position. The code uses `d3.select` and `d3.arc` from d3.v5, with all shapes positioned through SVG attributes and a centered group transform.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/601a06e7b6504217a8d36a2dd2104dd4?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
