{"version":"1.0","type":"rich","title":"LeWitt animate","description":"This example animates a grid of vertical lines, each moving upward at a random speed to create a lively, generative pattern. It renders SVG rectangles directly with JavaScript, setting each line’s fill to a bright green (#00FF66). The animation uses the Web Animations API via `element.animate`, applying an infinite, randomized `translateY` keyframe over a duration of up to 3000 milliseconds. A circular mask highlights the central region, while the page size adapts to the browser window, showing a minimal HTML/CSS approach without external libraries.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/048eabeafff048fa873b826aad615979?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
