{"version":"1.0","type":"rich","title":"svg smile","description":"A smiling face rendered in SVG shows two black eyes with white highlights that dart side to side, while a static arc forms the mouth. The animation uses chained `transition` calls on the eye highlight circles to shift their `cx` attributes over 1600 and 1400 milliseconds. Built with D3 v5, the code appends circles and a path using `d3.select`, `arc`, and shape helpers, with no external data source.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/ef1012607c934d5da1de74d1a0f89682?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
