This example reproduces a Sol LeWitt-style drawing using raw SVG elements and mask manipulation. The visualization renders a series of overlapping horizontal and vertical stripes by creating rectangles and applying circular SVG masks to confine their visibility, producing a geometric composition. The code uses DOM manipulation via `createElementNS` and `setAttribute` to construct the SVG, with two distinct masks (`circle-mask` and `circle-mask-2`) controlling different stripe patterns. The result is a monochromatic, grid-based artwork where varying rectangle heights and widths generate a rhythmic, minimalist pattern across the full viewport.
