{"version":"1.0","type":"rich","title":"Let's make a face with D3.js!","description":"This example demonstrates fundamental DOM manipulation with D3.js by constructing a smiley face from SVG primitives: a yellow circle, two eyes, a mouth drawn with `d3.arc`, and rectangular eyebrows. The face is centered in an SVG canvas via a `g` element and coordinate transforms. The eyebrows animate using chained `transition().duration()` calls, moving up and down over two-second intervals. The code relies on D3 v5 selection, attribute setting, and transition APIs to mutate SVG elements directly.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/7bbc7e4887df4a1eaa07f73370c186d2?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
