This visualization reproduces a Sol LeWitt art piece as a grid of horizontal and vertical lines, with both sets of lines partially masked by a central diamond shape. The code uses D3 v6 to append SVG rectangles in a loop, creating the line structure across the full browser window. Two SVG masks, rendered via `d3.symbol` with the diamond symbol type, selectively reveal or hide portions of the lines, producing the characteristic overlapping geometric pattern. The rendering is entirely SVG-based, with dimensions set to the window size.
