{"version":"1.0","type":"rich","title":"Let's make a face with D3.js!","description":"A self-contained D3.js animation builds a smiley face from SVG primitives—a yellow circle head, two eyes, rectangular eyebrows, and an arc-based smile. The face is centered using a coordinate transform, and the eyebrows bounce up and down in an infinite loop via chained `transition().duration()` calls. The example demonstrates fundamental DOM manipulation with the `select` and `append` API, along with the `arc` symbol for path generation, all rendered in a 960×500 SVG viewport.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/0b86351bc10f4c57bb037b83ab04e651?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
