{"version":"1.0","type":"rich","title":"Fork of Fork of SVG fundamentals","description":"This example demonstrates how SVG masks can create two distinct circular cutout effects on a grid of overlapping rectangles. One mask, defined with a black background and white circle, reveals only the vertical stripes; the other, with a white background and black circle, controls visibility of horizontal stripes. The code builds the full-screen SVG and all elements programmatically using `document.createElementNS` and `setAttribute` in vanilla JavaScript, without any external libraries. The result is a visual interplay of lines that form a transparent circular window at the center of the viewport.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/a09e2322e3364cc183b3e4f0bcb819f2?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
