{"version":"1.0","type":"rich","title":"Let's make a face with D3.js!","description":"This example builds a smiley face with D3.js, showing a yellow circle with eyes, eyebrows, and a mouth. The face is static, but the eyebrows animate by moving up and down using D3's transition system with `attr` transitions over 2000 milliseconds each. The code uses `d3.select` and `d3.append` to construct SVG elements, `d3.arc` to generate the mouth path, and `d3.transition` for the eyebrow animation. The SVG canvas is 960 by 500 pixels, and the face is centered using a group transform.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/f2c1e30034f945e0926a7b22c37a0207?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
