{"version":"1.0","type":"rich","title":"TD1","description":"Three circles—green, blue, and red—sit in a row on a gray SVG canvas. Clicking a rectangle starts a two-second animated transition that moves the red circle diagonally downward, followed by a second transition returning it horizontally. The red circle also turns black on mouseover, while the green circle responds to hover via a CSS class. Built with D3 v5, the example demonstrates selections, event handlers, and chained `transition.attr` calls, with no external data source.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/3a3f1e2d144b4bff958d5140546ac0ef?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
