{"version":"1.0","type":"rich","title":"Let's make a face with D3.js!","description":"This example creates a yellow smiley face from SVG primitives, then animates its eyebrows with a chained transition. Using D3.js v5, it selects the SVG, appends a centered group, and draws the face with circles, rectangles, and an arc-generated mouth. The `transition().duration()` calls move the eyebrow group upward and back, while `d3.arc` builds the mouth path from radius and angle parameters.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/2d37cf4aa7ab46d5ba44a4af1c2ebff0?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
