{"version":"1.0","type":"rich","title":"d3d3d3","description":"This example shows a full-screen pattern of intersecting horizontal and vertical bars, each rendered as a set of thin SVG rectangles. The bars are generated using `d3.range` and joined to `rect` elements, but only the central circular area is visible due to two SVG masks. The first mask reveals the horizontal bars through a white circle on a black background, while the second mask hides the vertical bars in the same region using a black circle on white. The result is a cross-hatched grid with a circular cutout, built with React and D3 v7.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/54fa919aad8b4653ab1b5f8f2a086954?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
