{"version":"1.0","type":"rich","title":"Fork of Fork of React Starter","description":"This example uses React and D3 to create a full-window SVG grid of horizontal and vertical stripes. A pair of circular SVG masks selectively reveals the underlying patterns: one circle is punched out of a white rectangle to show the vertical stripes, while a second white circle exposes the horizontal stripes. The code builds the masks and rectangles imperatively via D3's `select` and `join`, with `range` generating the stripe positions. The result is a simple, mask-driven optical illusion where the two stripe directions appear only within their respective circular regions.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/7acd997b1a414d888663d2c123a33e75?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
