This example reproduces a Sol LeWITT-inspired geometric composition using raw SVG and JavaScript. The visualization layers two sets of striped rectangles—one horizontal, one vertical—whose visibility is controlled by circular masks, creating a clean intersection of perpendicular lines within a central circle. The code constructs SVG elements programmatically via `document.createElementNS`, applying masks with a white circle on black and an inverted black circle on white to reveal alternating patterns. No external libraries are used; the rendering relies entirely on native SVG mask and rect primitives.
