{"version":"1.0","type":"rich","title":"Learn Selection","description":"A fruit bowl of five circles transitions through a sequence of changes: one circle shrinks and disappears, a circle changes from red (apple) to yellow (lemon), and another is removed. The example demonstrates D3's selection API with `selectAll`, `.enter()`, `.merge()`, and `.exit()`, using `.transition().duration()` to animate position, fill, and radius. It uses `scaleOrdinal` for color and radius mapping, and `range` to generate initial data.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/5517281eee43477197530892cb4d7eb7?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
