This visualization reproduces a Sol LeWitt-inspired vertical line composition, where a series of narrow rectangles fill the viewport. A circular mask restricts visibility, so only the lines inside a central circle are visible against the black background. The code builds an SVG scene using the browser’s native `document.createElementNS` API, generating each rectangle in a loop and applying the mask via a URL reference. No external libraries are used, and the layout adapts to the full window dimensions.
