{"version":"1.0","type":"rich","title":"Reproduction","description":"This visualization reproduces a geometric pattern using two overlapping circular masks to control the visibility of horizontal and vertical strips. The rendering relies on core SVG APIs, including `document.createElementNS` for constructing elements and `mask` definitions that hide or reveal rectangular bands across the canvas. One mask exposes a central circular region for the horizontal bars, while the inverse mask reveals vertical bars outside that circle. The result is a clean, intersecting grid pattern, implemented purely with JavaScript and SVG without external libraries.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/ab244996ba0d460699cf2e78460ae2b3?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
