This piece renders a grid of thin horizontal and vertical lines on an SVG canvas. The horizontal lines are clipped by a circular mask, creating a visible disk at the center while the vertical lines remain unclipped across the full canvas. Built with the SVG API and JavaScript, the code creates 50 horizontal and 50 vertical rectangles, applying a `<mask>` with a circle to limit the visibility of the former. The masks and shapes are generated procedurally.
