{"version":"1.0","type":"rich","title":"Let's make a face with D3.js!","description":"This D3.js v5 example builds an animated smiley face from scratch using SVG shapes. The sketch programmatically constructs a yellow circle for the face, black eyes, rectangular eyebrows, and an arc path for the mouth on a 960-by-500 canvas. Using D3's selection and transition APIs, the code animates the eyebrow group's vertical position in a repeating two-second cycle, moving it up 50 pixels and back. The example demonstrates fundamental DOM manipulation, including `select`, `append`, `attr`, and chained `transition().duration()` calls, to create a simple, lively character.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/6f175eacd5654550a60e8927a25c5aaf?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
