{"version":"1.0","type":"rich","title":"Let's make a face with D3.js!","description":"A yellow smiley face is drawn in SVG, with animated eyebrows that move up and down in a looping transition. The example demonstrates fundamental DOM manipulation by using D3 selections to create and position circles, rectangles, and an arc-based mouth via the `d3.arc` API. Built with D3 v5, it chains `.transition().duration(2000)` calls to animate the eyebrow group's transform attribute. The source code imports `select` and `arc` from D3, and renders everything within a fixed 960×500 SVG canvas.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/6c8a6913c4414a7dacccd1ecfb028768?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
