{"version":"1.0","type":"rich","title":"Simple rect","description":"Animated SVG rectangles appear in horizontal rows and grow to random heights and colors at regular intervals, then shrink and disappear. The visualization uses the d3 library’s `select`, `transition`, and `range` APIs to manage the lifecycle of each rectangle. Data is generated procedurally with JavaScript’s `setInterval` and `Math.random`, creating a constantly updating bar-like chart. The code defines a reusable `timePlot` function that handles enter, update, and exit states for smooth transitions.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/dc95773f301140869e6df5b66ff930eb?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
