{"version":"1.0","type":"rich","title":"Let's make a face with D3.js!","description":"A yellow smiley face with moving eyebrows demonstrates fundamental D3.js DOM manipulation and SVG rendering. The face is built using D3 selections to append circles, rectangles, and an arc-generated mouth path onto an SVG canvas. Eyebrow animation is achieved through chained `transition().duration()` calls that shift the eyebrow group's transform attribute up and down over two-second intervals. The code imports `select` and `arc` from the D3 v5 library, with fixed pixel values controlling facial feature positions and dimensions.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/a3a43382af2e4c21a4e36c0e53a886a8?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
