{"version":"1.0","type":"rich","title":"d3 selections","description":"This example demonstrates animated, data-driven updates of SVG circles using D3’s selection API. A set of circles oscillates vertically and horizontally, with their count varying sinusoidally over time. The code uses `d3.select`, `d3.range`, and the classic pre-v6 `selectAll`, `enter`, `merge`, and `exit` methods to manage additions, updates, and removals, running on a 60 FPS timer. It relies on D3 v6.6.1, rendering SVG with real-time animation.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/b8f245d7ede045b8870eb85cef364acb?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
