{"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 shapes, including a circle head, rectangular eyes, and an arc-based mouth. The face’s eyebrows animate vertically in a looping transition, moving up and then returning to their original position over four seconds. The code uses D3 v5 selections and the `arc` helper to generate the mouth path, while `transition().duration()` drives the eyebrow movement. The entire figure is centered within a 960×500 SVG canvas, with styling applied via an external stylesheet.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/f5b67f75e2954a9791acb4725443e9f3?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
