{"version":"1.0","type":"rich","title":"Let's make a face with D3.js!","description":"A smiley face built with SVG elements animates its eyebrows upward and back down in a loop. The example demonstrates fundamental D3.js DOM manipulation, using `d3.select` to append a yellow circle, two eyes, rectangular eyebrows, and an arc-based mouth constructed with the `d3.arc` helper. Two sequential `transition` calls with a 2000-millisecond duration move the eyebrow group via its `transform` attribute, showing basic chained animation without data binding. The face is centered on an empty 960×500 SVG canvas, with styling handled by an external stylesheet.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/b37c3b69554e4d1eb411f10840153b7b?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
