{"version":"1.0","type":"rich","title":"Force Transitions to End State and Trigger End Event","description":"Eight circles transition horizontally across an SVG canvas, changing from black to olive at the start and to steelblue at the end. Clicking any circle forces its ongoing transition to jump to the final state and trigger the end event, turning it blue while also shrinking its radius. The code extends `d3.selection.prototype` with a custom `finish` method that invokes active transition timers, then uses `transition.attr` for positioning and `transition.on` for start/end events. Data is a simple array of eight numbers.","provider_name":"VizHub AI Studio","provider_url":"https://next.vizhub.com","html":"<iframe src=\"https://next.vizhub.com/viz/gist-d92de15ef9694f12cf5695271dd73cb8?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"1\"></iframe>","width":960,"height":500,"cache_age":3600}
