{"version":"1.0","type":"rich","title":"D3 smily","description":"This example renders a yellow circle as a smiling face over an SVG canvas using D3 and React. The code constructs the face with circles for eyes and a donut-shaped arc path for the mouth, then animates the eyebrows via chained `transition().duration()` calls on a group element. Using D3’s `arc` generator and SVG attributes, the visualization demonstrates basic shape composition and timed transforms without external data.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/9f37a36b71ba4e55b103d57cfb2e8b8b?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
