This example reproduces a Sol LeWitt-inspired wall drawing using raw SVG and JavaScript. It presents a grid of horizontal and vertical stripes that intersect through two circular masks, creating a layered composition with a central white circular void and a black circular overlay. The code constructs SVG elements directly via the DOM API, including `rect` shapes and two custom `<mask>` definitions, to alternate stripe visibility. A total of 200 rectangles are generated programmatically, with no external libraries or frameworks, relying solely on browser-native SVG rendering to achieve the geometric effect.
