{"version":"1.0","type":"rich","title":"Fork of Fork of Sol LeWitt with d3js 2","description":"A grid of alternating horizontal and vertical black lines is masked so that only a circular area is visible. The example uses D3 v6 to generate SVG rectangles with `selectAll`, `data`, and `join`, and applies two SVG masks to invert the visibility pattern. `d3.range` creates the sequence for positioning, while masks define a central circle where lines appear or disappear.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/a31cda726297430e83c54ba9324c75e0?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
