{"version":"1.0","type":"rich","title":"+","description":"A smiling face is drawn as a static SVG, then its mouth widens and narrows in an animated loop using D3. The static portion uses basic SVG shapes—a yellow circle with a black stroke for the head and two smaller black circles for the eyes. The animated mouth is generated with D3's `arc` geometry, and its start and end angles are modified over time inside a `d3.timer` callback. The mouth shape is redrawn as a path using the updated arc each frame.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/2c687609b83b449ea87f79a019c1dc06?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
