{"version":"1.0","type":"rich","title":"Moving Circles - using JOIN v1","description":"Fifteen circles animate in a wave-like pattern across the screen, their vertical positions and radii oscillating sinusoidally over time. The visualization uses D3 v6’s `selectAll`, `data`, and `join` methods to bind and update circle elements on an SVG canvas, with a `setInterval` driving the animation at 60fps. Data is generated procedurally via `range` and trigonometric functions, demonstrating the core update pattern of D3’s data-join without explicit enter or exit handling.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/c4616a6f94604ceba261e2b0fb02bf46?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
