{"version":"1.0","type":"rich","title":"Let's make a face with D3.js!","description":"A yellow smiley face drawn with D3.js demonstrates fundamental DOM manipulation as its eyebrows animate up and down. Using D3 v5 and SVG elements, the example builds the face from a circle, two eye circles, rectangular eyebrows, and an arc-based mouth via the `d3.arc()` generator. A chained `transition()` with `attr()` calls moves the eyebrow group sequentially over two-second durations, triggering the wiggle effect. Static geometry is appended through selections, while animation relies on D3's built-in transition API.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"","width":960,"height":500,"cache_age":3600}
