This example renders an abstract geometric composition inspired by Sol LeWitt’s wall drawings, built with vanilla JavaScript and the SVG API. It shows a 1000×700 canvas filled with alternating vertical and horizontal stripes that appear to weave through a central hourglass-like polygon shape. Two SVG masks define the visible regions: the first mask applies to 50 vertical red stripes, the second to 50 horizontal red stripes, creating a layered visual effect where the pattern changes orientation within the polygon. The code constructs the SVG elements dynamically using `createElementNS`, with mask polygons and stripe rectangles, demonstrating a low-level approach without external libraries.
