This example reproduces a Sol LeWitt-inspired drawing by rendering a grid of vertical and horizontal stripes that intersect through two complementary circular mask regions. The visualization uses raw SVG DOM manipulation in vanilla JavaScript, creating 100 vertical rectangles masked by a circle cutout and 100 horizontal rectangles masked by an inverted circle. The masks, defined via SVG `mask` elements with white and black fills, reveal alternating stripe patterns. The result is a geometric interplay of lines and negative space, rendered dynamically to fill the browser window.
