{"version":"1.0","type":"rich","title":"Fork of HTML Starter","description":"This example creates an SVG visualization that displays a series of horizontal stripes, with a circular mask revealing the central portion of the pattern. The visualization uses the HTML5 Canvas API indirectly through SVG elements, specifically manipulating SVG `rect` elements and a `mask` definition. The code generates 100 rectangles, each 10 pixels tall and spaced 20 pixels apart, all constrained by a `circle-mask` that creates a circular viewport. The mask itself contains a white background `rect` and a black `circle` positioned at the center of the viewport, effectively cropping the striped pattern into a circular shape.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"","width":960,"height":500,"cache_age":3600}
