{"version":"1.0","type":"rich","title":"Making a face with D3","description":"A yellow smiley face with eyes, eyebrows, and a mouth is rendered in an SVG canvas. The eyebrows animate by moving upward and then returning to their original position over two separate two-second transitions. Built with D3 v5, the code uses selection methods like `select`, `append`, and `attr`, and leverages `d3.arc` to generate the mouth path. The animation is driven by chained `transition().duration()` calls, while geometry is positioned using numeric constants for spacing and offsets.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/40c6e0ebd6314ba4afda757d3b069627?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
