{"version":"1.0","type":"rich","title":"Fork of Hello HTML","description":"This example shows a blue square rendered within an SVG element, with a circular cutout revealing the page background. A mask defined in SVG `<defs>` uses a white rectangle and a black circle to hide the circle’s area. The page uses plain HTML and SVG’s built-in mask API, with no external JavaScript libraries. The SVG is 200 by 200 pixels, and the mask applies directly to the rectangle’s `fill` via the `mask` attribute.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/f2e54da196c64d72b55655851a0354d8?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
