{"version":"1.0","type":"rich","title":"Let's make face with d3","description":"A yellow smiley face is drawn in SVG, with a circular head, two eyes, and a curved mouth defined using `d3.arc()`. The eyebrows, rendered as rectangles, animate upward and back down via chained `transition().duration()` calls on their group’s `transform` attribute. The code uses D3 v6 selections and `parseFloat`/unary plus to read SVG dimensions, positioning all features relative to the center.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/133f3d902968443baf2e7e305da8cb49?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
