This example reproduces a Sol LeWitt-style geometric drawing using SVG, showing a grid of horizontal and vertical stripes that are masked to reveal a central circle. The visualization dynamically fills the browser window by setting the SVG width and height to the viewport dimensions. It constructs two SVG masks with white and black circles and rectangles, then renders 100 horizontal and 100 vertical stripe rectangles, each referencing a mask to clip the pattern. The code uses the DOM API `document.createElementNS` to build SVG elements programmatically with JavaScript.
