This interactive geometric visualization uses D3 v7 to reproduce a Sol LeWitt art piece. The sketch renders overlapping horizontal and vertical stripes across the full browser window, using D3 selection methods `selectAll()` and `join()` with `range()` to generate 100 rectangles in each direction. SVG masks with circular cutouts create two concentric masked regions, with a black circle mask revealing the horizontal stripes while a white circle mask reveals the vertical stripes in the center. The artwork displays a minimalist grid pattern where the two stripe orientations intersect within the central circular area.
