{"version":"1.0","type":"rich","title":"Making Selections Move","description":"A grid of circles animates continuously, with each circle moving vertically and changing radius over time based on a sine wave. Using D3 v7 and React, the code generates new data arrays at 10-millisecond intervals via `setInterval`, and a data join with `.selectAll('circle').data(data).join('circle')` updates the SVG elements smoothly. The `makeData` function computes x positions and sine-based y and radius values, while `vizData` handles the rendering, demonstrating a seamless approach to animating selections without explicit enter or exit handling.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/2fcd37a830fd45bb980c0f008ab8d83c?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
