{"version":"1.0","type":"rich","title":"D3 Selection Exploration","description":"This example demonstrates data joins in D3 by animating a set of circles based on sine functions, with both the count and positions updating continuously. Drawn as SVG elements, it highlights the difference between the pre-v6 enter/merge/exit pattern and the modern `.join()` shorthand for binding data. The animation runs on a 60fps interval, using `select`, `range`, and chained attribute setters to update circle radius, x, and y coordinates in real time.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"","width":960,"height":500,"cache_age":3600}
