{"version":"1.0","type":"rich","title":"Let's make a face with D3.js!","description":"The smiley face drawing uses D3.js v5 to build and animate SVG elements, with eyebrows and a small circle that move in looping transitions. The code constructs a yellow head, eyes, eyebrows, and a mouth via `append()` and `attr()`, using `arc()` for the mouth path and `transition()` sequences with `.duration()` and `.on(\"end\")` callbacks to repeat animations. The animation alternates the eyebrow group’s `transform` translation between two positions and rotates the circle’s `transform`, demonstrating fundamental DOM manipulation and timed attribute tweening in a simple, playful scene.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/4486a7e99fbf475ca029f1ea2dc85892?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
