{"version":"1.0","type":"rich","title":"sole lowit reproduction vertical","description":"A full-screen SVG composition displays 100 horizontal black rectangles layered vertically, with a circular mask revealing only a centered 200-pixel-radius region defined by white and black mask shapes. The code dynamically generates the SVG via the Document Object Model (DOM) `createElementNS` API, setting the mask’s rectangle and circle to control visibility. Each rect is assigned the mask using the `url(#circle-mask)` reference, creating a bold, striped window effect against a white background. The example demonstrates procedural SVG shape construction and masking without external libraries, relying purely on native browser APIs.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/c5314bc72fd1442bb9d1d66b9be408a2?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
