{"version":"1.0","type":"rich","title":"Let's make a face with D3.js!","description":"D3.js builds a smiley face from SVG shapes: a yellow circle, two eyes, rectangular eyebrows, and an arc-shaped mouth. The code uses `d3.select` and `d3.arc` to construct the face, then applies a chained `transition().duration(2000)` to repeatedly move the eyebrow group up and down, creating an animated expression. All elements are centered via a translation transform.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/1e6b61cb01a14cd585f9da83f312d19c?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
