{"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 building a smiley face whose eyebrows animate up and down. The code creates the face using SVG primitives—a yellow circle, two eyes, and rectangular eyebrows—all grouped and positioned through chained `.attr()` calls and transform translations. The animation is achieved by chaining two `.transition().duration(2000)` methods on the eyebrow group, which alternately shifts its vertical offset. Using D3 v5 and the `select`, `arc`, and `transition` APIs, the example shows how to construct and animate simple shapes directly in an SVG canvas.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/f8524b74f55040f18622f0818e5b0fdb?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
