This example shows a generative reproduction of a Sol LeWitt wall drawing, built entirely with inline SVG and the DOM API. It draws 100 horizontal and 100 vertical striped rectangles across the viewport, and uses two SVG masks to carve a central circular reveal: the first mask clips the horizontal bars, the second masks the vertical bars. The result is a grid of lines that intersect only inside the circle. The code uses `document.createElementNS` and `setAttribute` for all SVG construction.
