{"version":"1.0","type":"rich","title":"Let's make a face with D3.js!","description":"This example demonstrates fundamental D3.js DOM manipulation by constructing a smiley face from SVG shapes, with a gentle animation of its eyebrows. The code builds a yellow circle head, eyes, and a mouth using D3’s `select`, `attr`, and an `arc` generator for the path. The eyebrow rectangles transition vertically via chained `transition().duration(2000)` calls, moving them down and back up. It uses D3 v5, rendering to a static SVG canvas with no external data, focusing purely on programmatic element creation and animation.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/36a53683849242c6ba72b7ed95c6e465?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
