{"version":"1.0","type":"rich","title":"Shapes and Colors with SVG and CSS","description":"A smiling face rendered in SVG uses D3 v5 to construct circles, rectangles, and an arc-based mouth. Static yellow and black shapes form the head and eyes, while CSS transitions animate the eyebrows upward and downward over two-second intervals. The code directly manipulates SVG attributes such as `cx`, `r`, and `d` with an `arc` generator, and uses `transition.attr` to shift eyebrow positions.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/0f774d9e8aea4cceba211a1101b3334c?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
