{"version":"1.0","type":"rich","title":"Let's make a face with D3.js!","description":"An animated yellow face with bouncing eyebrows and a morphing mouth is drawn in SVG using D3.js v5. The face is composed of circles, rectangles, and an arc-generated path, all centered within a 960×500 viewport. Transitions animate the eyebrow group’s vertical position over two seconds and change the mouth’s inner radius between 150 and 0 over three seconds, looping indefinitely via a `while(true)` block. The code uses `d3.select`, `d3.arc`, and chained `transition().duration()` calls to orchestrate the continuous motion.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"","width":960,"height":500,"cache_age":3600}
