{"version":"1.0","type":"rich","title":"Concept of Merge_Join ","description":"This example animates a series of circles that move vertically and change radius over time, demonstrating dynamic data binding with D3. The visualization updates every 200 milliseconds, recalculating positions and sizes based on a sine wave. It uses D3’s `selectAll`, `data`, and `join` to bind new data arrays to SVG circle elements, with values generated by `range` and trigonometric functions. The rendering is SVG-based, and the animation runs through a JavaScript `setInterval` loop.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/cdc33cd627cd4d2597e69887245e1d54?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
