{"version":"1.0","type":"rich","title":"DV smile","description":"This example renders a smiling face as a static SVG with animated eyebrows. A yellow circle forms the head, with blue eyes, a mouth created via `d3.arc()`, and two rectangles for eyebrows that move upward and back down using chained `transition().duration()` calls. The visualization uses D3 v7’s `select`, `append`, and `attr` methods to build the SVG elements, with coordinates computed from the SVG’s width and height attributes. The eyebrows repeatedly animate between two vertical positions, creating a playful, looping motion.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/bcedd0b92690479a83acd035a3b62f26?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
