{"version":"1.0","type":"rich","title":"Episode 3: Sol LeWitt in Vanilla JavaScript version 5","description":"A colorful grid of thin vertical rectangles fills the screen, each one continuously rotating 360 degrees via the Web Animations API’s `Element.animate()`. A large white circle overlays the center, while a second set of horizontal rectangles, masked by an SVG `mask` containing a circle, reveals only inside that circular region. The piece generates random RGB fill colors for each vertical bar and uses a fixed count of 200 elements, with SVG attributes and styles set imperatively through JavaScript. The animation runs infinitely with a 2000-millisecond duration per rotation.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/d3b8950472cd485980c4fe0c452db076?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
