This piece reproduces a Sol LeWitt drawing using D3 to render alternating horizontal and vertical striped rectangles. It uses two SVG masks to create a cross-hatched effect: the first mask shows white bars on black, the second shows black bars on white, and each displays a series of 100 geometric symbols across the center. The code employs `d3.select`, `d3.range`, and the `d3.symbol` API to draw the paths, generating a patterned composition that responds to the browser window size.
