This example recreates Sol LeWitt’s generative art using raw SVG elements created through the DOM API. The piece displays a grid of horizontal and vertical bars whose placement and thickness are computed from the viewport dimensions. A circular mask, defined as a separate SVG mask, applies a hole to the vertical bars, while a second mask with a white circle reveals the horizontal bars. The result is a dynamic, mask-based interplay of intersecting lines that echoes LeWitt’s systematic, rule-driven aesthetic. The code generates rectangles and circle masks entirely via JavaScript’s `document.createElementNS`, with no external libraries.
