{"version":"1.0","type":"rich","title":"Fork of HTML Starter","description":"This example creates a full-window SVG scene using native JavaScript and the DOM API, without any external libraries. It draws 100 horizontal and 100 vertical rectangles to form a grid, with horizontal bars partially obscured by an SVG mask that reveals a central circle. The mask combines a black background rect with a white 200-radius circle at the center, so only the bars inside that circle are visible. The rendering approach relies on `document.createElementNS` to build SVG elements and `setAttribute` for dynamic sizing based on `window.innerWidth` and `window.innerHeight`.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/c120a6bca5054c3d96edcabd800f7cdd?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
