{"version":"1.0","type":"rich","title":"Let's make a face with D3.js!","description":"This example uses D3.js to build an animated smiley face in SVG, whose eyebrows lift and lower in a looping transition. It shows fundamental DOM manipulation by selecting an SVG element, appending grouped shapes, and binding attributes for the face’s circles, rectangles, and an arc-based mouth. The animation relies on chained `transition().duration()` calls to move the eyebrow group’s transform. Specific APIs include `select`, `append`, `attr`, and `arc` from D3 v5, with coordinates computed from hardcoded spacing and offset values.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/339926bd458f469f8e90d5bcb8573b8f?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
