{"version":"1.0","type":"rich","title":"Let's Make a Face Part I","description":"A simple animated smiley face is constructed using D3.js, with a yellow circular head, two eyes, eyebrows, and a partial arc mouth. The eyebrows animate upward and downward in a repeating cycle, adding a subtle expressive motion to the otherwise static face. The visualization is built entirely with SVG primitives—`circle`, `rect`, and `path` elements—and relies on D3's `transition` API to animate the eyebrow transform over two-second intervals. The arc for the mouth is generated using D3's `arc` function, which produces a path for the specified inner and outer radii and angle range.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/f7d5f201792e4e4f95443a8ef73a2018?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
