This example renders a simplified Sol LeWitt-inspired geometric composition using vanilla JavaScript and the SVG DOM API. It creates a full-screen dark green background, centers a bright green circle, and overlays alternating vertical rectangles across the width to produce a striped pattern that masks the circle. The code computes element coordinates from `window.innerWidth` and `window.innerHeight`, and uses `document.createElementNS` to construct the SVG nodes directly without any external libraries.
