{"version":"1.0","type":"rich","title":"Exercise v2","description":"This example animates five circles on a black background, each starting at radius 0 and expanding to its target size while updating its position. The circles use distinct colors and opacity, with staggered entrance delays and a faster linear transition for position updates. Built with D3 v7, it employs `transition`, `easeLinear`, and data joins via `selection.join()` to handle enter, update, and exit states. The visualization is a reproduction of a Sol LeWitt art piece, with the code defining explicit x, y, and radius values for each circle and rendering them as an animated SVG.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"","width":960,"height":500,"cache_age":3600}
