{"version":"1.0","type":"rich","title":"Let's make a face with D3.js!","description":"This example creates a smiling face from basic SVG shapes, with its eyebrows repeatedly moving up and down. It demonstrates fundamental D3.js DOM manipulation by appending and styling circles, rectangles, and a path for the mouth. The code uses `d3.select`, `d3.arc` for the mouth, and chained `transition().duration()` calls to animate the eyebrow group’s transform attribute. The face is centered via a translated `<g>` element, with eye spacing and offsets defined as numeric constants.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/b83d64ac42684364abd6b28742d067bc?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
