{"version":"1.0","type":"rich","title":"Let's make a face with D3.js!","description":"This is an animated smiley face built with D3.js (v5) that demonstrates fundamental DOM manipulation. The face is constructed from SVG primitives, including a yellow circle for the head, two circles for eyes, and a path created with the `d3.arc` API for the mouth. The example uses D3's `transition().duration(2000)` to animate the eyebrows (rectangles) moving up and down in a two-step sequence. The entire composition is centered within an SVG canvas using an SVG transform.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/ea4349e9387c4812b7c53605c820781a?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
