{"version":"1.0","type":"rich","title":"graph2.js!","description":"This example uses D3.js (v5) to draw an animated smiley face in SVG. It shows a yellow circle with two eyes and a mouth, whose eyebrows move up and down via chained `transition()` calls. The code constructs the face using `select`, `append`, and `attr`, and generates the mouth path with the `arc` API. The animation runs on page load with a 2-second duration per eyebrow movement.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/26396072f5274174988fbe2681fbd182?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
