{"version":"1.0","type":"rich","title":"Let's make a face with D3.js!","description":"This example builds a smiley face with D3.js, demonstrating fundamental DOM manipulation and animated transitions. Using SVG elements, it constructs a yellow circle head, two eyes, rectangular eyebrows, and an arc-shaped mouth via the `arc()` generator. The code selects the SVG and appends groups to position features, then uses `transition().duration()` to animate the eyebrows upward and back down over four seconds. The example showcases D3 v5’s data-join-free approach, relying on direct selection, attribute setting, and chained transitions to create a simple, expressive character animation.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/f38f6d16ad3649868af7de30fba9040d?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
