This example reproduces a Sol LeWitt drawing by layering two sets of striped rectangles inside an SVG canvas. One set of horizontal stripes is masked by a central white circle, while the other set of vertical stripes uses an inverted mask, creating intersecting grid patterns. The code uses the SVG API to create elements and masks, manipulating `createElementNS` and attributes. It renders the entire browser viewport, defining masks and loops to generate the grid geometry.
