{"version":"1.0","type":"rich","title":"D3 intro","description":"D3 intro reproduces a Sol LeWitt art piece by rendering 100 horizontal bars across the screen. D3 selections and the `join` pattern generate the rectangles using the `range` function. Two SVG masks, `circle-mask` and `circle-mask-2`, create a circular cutout through the bars while leaving the surrounding lines visible. The second mask applies a black circle to an otherwise white background, producing a negative space effect.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/7d2af9941f084f098d1c75ea5c5bd83b?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
