{"version":"1.0","type":"rich","title":"so lewit reproduction D3.js fundamental","description":"This example reproduces a Sol LeWitt–style drawing using D3.js. It generates a grid of horizontal and vertical rectangles, each masked to reveal a circular cutout at the center of the screen. The visualization uses D3’s `select`, `range`, and data joins to create 100 rects in each direction, with SVG masks (`url(#circle-mask)`) alternating black and white fills to control visibility. The code relies on D3 v7 and renders entirely as SVG, filling the full browser viewport with no external data.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/dc6edc64c5f94b92b437ba4f12856178?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
