{"version":"1.0","type":"rich","title":"Mouse follower React","description":"A smiley face rendered as SVG responds to no user input, but its eyebrows perform a looping animation, moving down and up repeatedly. The demo uses D3 v5 selections and transitions to manipulate SVG elements, including circles for the face and eyes, rectangles for eyebrows, and a path for the mouth via the `arc` generator. The code structures the face using a centered group with translated subgroups for the eyes and eyebrows, while `transition.attr` with durations animates the eyebrow group’s vertical position. Built with React, the example runs in a plain HTML page with D3 loaded via CDN.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/b44c088842b7416d86d881572825de4a?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
