{"version":"1.0","type":"rich","title":"svg mask","description":"This example demonstrates the visual effect of SVG masks by layering horizontal and vertical stripes over a full-viewport canvas. It creates two circular masks, one with a white circle on a black background and the other with a black circle on a white background, then applies them to alternating sets of 50 thin rectangles. The code builds the entire scene programmatically using the Document Object Model (DOM) methods such as `createElementNS` and `setAttribute`, without any external libraries, and renders everything directly in SVG.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/6995f5b42c9f4e908bafcf84e1d1a8ff?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
