{"version":"1.0","type":"rich","title":"Fork of D3 Implementation","description":"Two sets of 100 striped rectangles overlay each other at right angles, revealing a circular window at the center through SVG masks. Built with d3.select and d3.range, the code generates horizontal and vertical bars filled with alternating colors. Each set applies a mask combining a full-screen rect with a 200-pixel-radius circle, one using a white circle on black and the other inverting the colors. The result forms a crosshatched grid visible only inside the overlapping circular region, rendered as vector SVG graphics scaled to the full browser viewport.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/436186cd6636406aa2d5cee4d3d6eab3?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
