This example reproduces Sol LeWitt’s minimalist wall drawing as an interactive SVG composition. It generates a grid of alternating horizontal and vertical rectangles, with a circular mask revealing only the central region of the layered shapes. The code uses the DOM API’s `createElementNS` to construct SVG elements directly, setting attributes like `width`, `height`, and `mask` programmatically. No external libraries are required, and the rendering adapts to the full browser viewport, creating a stark black-and-white geometric pattern inspired by the artist’s systematic approach.
