This example reproduces a Sol LeWitt-inspired drawing using raw SVG and JavaScript, generating a grid of horizontal and vertical bands across the full viewport. It employs two SVG `mask` elements with circles at the center to selectively reveal the overlapping stripes, creating a circular intersection pattern. The code constructs all elements dynamically via the DOM API, setting the window dimensions as the canvas size and drawing 100 rectangles in each direction. This fork adapts the original concept to a vertical orientation, using nested rects and masks to achieve the geometric effect.
