This interactive SVG artwork creates a grid of vertical and horizontal lines, with a circular void in the center formed by masking. The visualization uses SVG masks (`circle-mask` and `circle-mask2`) to show vertical lines inside a white circle and horizontal lines outside it, resulting in a dynamic, layered composition. Built with vanilla JavaScript using `document.createElementNS`, it generates 100 rectangles per axis, with the central circle positioned at the viewport center. The design adapts to the browser window size, demonstrating a creative use of SVG masking for generative art.
