{"version":"1.0","type":"rich","title":"first D3","description":"This example shows a fullscreen grid of 200 vertical rectangles, each a random color, animating upward indefinitely. The rendering approach uses raw SVG elements created via the `document.createElementNS` API, with styles set directly on each rectangle. The animation relies on the Web Animations API (`element.animate`) to translate each rectangle along the Y-axis with randomized durations and infinite iterations. No external JavaScript libraries are used; the page is a minimal HTML document with inline CSS and JavaScript, demonstrating basic D3-free DOM manipulation for a generative visual effect.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/26f486e2d0ea477b87796d46023cc772?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
