{"version":"1.0","type":"rich","title":"Let's make a face with D3.js!","description":"A smiley face with animated eyebrows demonstrates basic DOM manipulation with D3.js. The visualization renders SVG shapes—a yellow circle, eyes, rectangular eyebrows, and an arc-based mouth—centered on a 960×500 canvas. Using `d3.select` and `d3.arc`, the code constructs each facial feature programmatically. A chained `transition` with 2000-millisecond durations moves the eyebrow group upward and back, creating a blinking-like motion. The example showcases fundamental D3 v5 selections, attribute setting, and animation without external data, relying purely on geometric constants for positioning.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/227a0295d3ed4b1989ee702641a4f915?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
