A fork of a Sol LeWitt reproduction uses D3 to generate layered horizontal and vertical striped rectangles across the full viewport. Two SVG masks create geometric cutouts: a white diamond-shaped hole in one mask and a black circular hole in another, revealing intersecting grid patterns. The code employs d3.select, d3.range, d3.symbols, and d3.symbol to draw paths and shapes, with masking applied via SVG mask elements. The example renders entirely in SVG, driven by window dimensions.
