{"version":"1.0","type":"rich","title":"Forking","description":"A smiling face rendered in SVG continuously raises and lowers its rectangular eyebrows through chained D3 transitions. The example demonstrates fundamental DOM manipulation with D3 v5, using selection methods like `append` and `attr` to build the face from basic shapes—a circle for the head, arcs for the mouth, and rectangles for the brows. The code explicitly uses `d3.arc` and `d3.select` to construct the mouth path and animate the eyebrow group’s `transform` attribute over timed durations.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/618f4fcf66fc45a0a7ae844e77dfbd74?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
