{"version":"1.0","type":"rich","title":"Fork of React Starter","description":"A grid of thin black horizontal and vertical strips forms a woven texture across the full viewport. Two circular masks reveal the underlying pattern: the first mask, created with a white rectangle and black circle, isolates a circular region where vertical strips appear; the second mask, using a white circle on a transparent background, exposes horizontal strips within its boundary. The example uses D3 selections with `join` and `range` to generate 100 rectangles per orientation, and React’s UMD build to mount the document, rendering entirely as SVG.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/09a545d5086f4d69a91e0fa89c417424?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
