{"version":"1.0","type":"rich","title":"mask experiments","description":"This example demonstrates the interplay of two complementary SVG masks. It first shows a set of horizontal stripes visible only within a circular window, then displays vertical stripes that are hidden inside the circle while remaining visible outside it. The piece creates a stark geometric contrast between the two masked regions. The visualization is generated entirely with the SVG `mask` element and basic `rect` and `circle` primitives, using white and black fills to define luminosity. The code dynamically constructs one hundred stripes for each orientation, with the masks applied via URL references to `#circle-mask` and `#circle-mask-2`.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/b0fc79b64a9347e5ac64fbdfe4c27bca?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
