This piece creates layered horizontal and vertical bands that pass through stencil-like openings formed by rotating geometric symbols. The composition is generated by drawing 20-pixel-wide rectangular strokes across the full canvas, masked by two inverted patterns built from D3's `symbol` generator. Using D3 v7 APIs such as `select`, `range`, `symbols`, and custom mask rendering, the artwork changes with the browser window’s dimensions, reproducing a generative Sol LeWitt aesthetic through pure SVG output.
