{"version":"1.0","type":"rich","title":"D3 test","description":"This example shows a simple yellow face built from SVG shapes, with eyes that blink through a repeating eyebrow animation and a smiling arc-shaped mouth. The code uses D3 v6 selections to append circles, rectangles, and a path to an SVG canvas, while the mouth is drawn with the `d3.arc` helper. A two-stage `transition` chain animates the eyebrows downward and back, demonstrating chained timing. The face is centered using an SVG transform, and static styling comes from the included stylesheet.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/0264bff9b29649699e3690030a3a961c?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
