{"version":"1.0","type":"rich","title":"D3 Selections","description":"Two autonomous SVG panels animate circles whose positions and radii shift continuously via a sinusoidal data generator. Each frame, `setInterval` updates data arrays produced by `makeData`, while `vizDraw` uses D3 selections and the `join` method to bind and redraw circles. The upper panel renders black circles on white, the lower white circles on black, driven by sine and cosine functions with a time-stepped parameter. Both SVGs redraw at 60 frames per second.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/3a6aac27ace247c39b872bc2f3725410?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
