{"version":"1.0","type":"rich","title":"Let's make a face with D3.js!","description":"This example builds a smiley face from basic SVG shapes using D3.js, demonstrating core DOM manipulation and selection techniques. The code appends a yellow circle for the head, two eyes, rectangular eyebrows, and an arc-based mouth inside a centered group element. The eyebrows animate by chaining `transition` calls with a two-second duration, moving them upward and back down in an infinite loop. The implementation uses D3’s `select`, `append`, `attr`, and `arc` APIs to construct and position all elements.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/c2ed7fd073514fbda8514e0cc96361c6?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
