{"version":"1.0","type":"rich","title":"Let's make a face with D3.js!","description":"This example uses D3.js to build a smiley face in an SVG container, with eyebrows that animate up and down via chained transitions. The code selects the SVG, appends a centered group, and draws the yellow circle head, eyes, rectangular eyebrows, and a mouth path created with the `d3.arc` generator. Eyebrow motion is achieved through two sequential `transition().duration(2000)` calls that shift the eyebrow group’s transform attribute. The rendering relies on SVG elements and D3’s `select` and `arc` methods, with fixed numeric constants for spacing and sizing.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/1346850f99fb40829d58f34d28a4f7d7?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
