{"version":"1.0","type":"rich","title":"circle mask","description":"A full-screen SVG displays 100 horizontal stripes alternating in height across the viewport, with a circular mask revealing only the central region. The mask is defined as an SVG `<mask>` containing a white rectangle and a black circle, applied to each stripe via the `mask` attribute. The visualization uses raw DOM manipulation with `document.createElementNS` and `setAttribute` to construct the SVG elements dynamically in JavaScript, without any external libraries.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/bf17ffcca3084a628f71284f043befbb?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
