{"version":"1.0","type":"rich","title":"Let's make a face with D3.js!","description":"A smiley face drawn with SVG shapes animates its eyebrows upward and back down. The example demonstrates fundamental DOM manipulation with D3.js, using `d3.select` to append a yellow circle, two eye circles, arc-based mouth and eyebrow paths, and a rectangular eyebrow. D3 transitions (`transition().duration(2000)`) animate the eyebrow group’s vertical position. The code imports `select` and `arc` from D3 v5, rendering to an SVG canvas with hard-coded dimensions.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/781f6fc4d0a942ef8e47c9df4710af69?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
