{"version":"1.0","type":"rich","title":"Fork of Circles with D3","description":"This example demonstrates a visual effect of horizontal and vertical lines intersecting within a circular mask, creating a woven or grid-like pattern. The code uses vanilla JavaScript and the SVG API to construct a mask element with a white circle over a black rectangle, then renders 100 horizontal and 100 vertical line segments. These lines are drawn using `createElementNS` and `setAttribute` rather than a D3 data join, despite the D3 library being listed as a dependency. The resulting graphic showcases a clean geometric composition where the mask isolates a circular region of the grid.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/5a341ad2420a4363b8e218befba22b2d?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
