{"version":"1.0","type":"rich","title":"Bowl of Fruit: Object Constancy","description":"Five apples appear in a row, then fade and slide in response to timed data updates that remove fruits or change an apple into a lemon, preserving each circle’s identity via a stable `id` key. The example demonstrates D3’s object constancy pattern by using `selection.data` with a key function, `enter`, `merge`, and `exit` selections, plus chained `transition` calls to animate radius and x-position over one second. Rendering uses SVG circles with d3-color scales for fill and size.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/540d5278beb245d49b57c9f4e71e73b1?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
