{"version":"1.0","type":"rich","title":"inverse masking done","description":"This example demonstrates inverse masking with SVG, where intersecting horizontal and vertical striped rectangles reveal a circular cutout at the center. Two masks are defined: one with a white circle on a transparent background, and another with a black circle over a white rectangle. The code builds 100 horizontal and 100 vertical rectangle strips, applying each mask to create a cross-hatch effect where the circle appears transparent. It uses plain JavaScript to manipulate SVG elements directly, with the `<mask>` element and `url(#...)` references controlling visibility.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/881173f1639d4c7a885c2e2c05515bdf?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
