{"version":"1.0","type":"rich","title":"Let's make a face with D3.js!","description":"A yellow smiley face is drawn with SVG shapes, and its eyebrows animate up and down in a looping motion. The example demonstrates fundamental D3.js DOM manipulation by appending circles, rectangles, and an arc-generated mouth to an SVG canvas. It uses the `d3.select` and `d3.arc` APIs, along with chained `transition().duration()` calls to animate the eyebrow group's transform. The code imports from D3 v5 and renders entirely with SVG elements on a 960 by 500 canvas.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"","width":960,"height":500,"cache_age":3600}
