{"version":"1.0","type":"rich","title":"Fork of HTML Starter","description":"This example uses raw JavaScript and the SVG API to dynamically construct a full-window visualization. It creates two distinct masks on an SVG canvas: a white circle on a transparent background and a white rectangle with a black circular hole at the center. The code then generates 100 horizontal and 100 vertical thin rectangles, applying these masks to reveal a grid-like pattern of intersecting lines against a plain background. The result is a geometric composition built entirely through procedural DOM manipulation without any external libraries.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"","width":960,"height":500,"cache_age":3600}
