{"version":"1.0","type":"rich","title":"Fork of Fork of Fork of React Starter","description":"This visualization shows a grid of horizontal and vertical bars rendered as SVG rectangles, with a circular region left visibly unobscured at the center of the viewport. The code uses D3’s `select` and `range` functions to generate 100 bars in each orientation across the full window dimensions. Two SVG masks, created via D3’s `append` and `attr` methods, control visibility: one mask contains a white circle over a black background, while the other inverts this pattern. The bars display fine black stripes outside the circular mask area, producing a clean intersecting line pattern.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/9524833d8545420cb30abd23d0508d45?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
