This visualization reproduces a Sol LeWitt art piece by rendering intersecting horizontal and vertical lines on an SVG canvas. A central circle is isolated through two SVG masks, creating a geometric interplay where line patterns alternate between appearing within and outside the circular boundary. The code uses vanilla JavaScript with the SVG DOM API, generating 100 rectangle elements per axis and applying masks (`circle-mask` and `circle-mask-2`) to control visibility. The result mirrors LeWitt’s systematic, rule-based aesthetic without external libraries.
