This visualization recreates a Sol LeWitt-inspired geometric drawing using pure SVG. It shows a grid of vertical and horizontal black lines intersecting across the full screen, but with their density inverted between the center and the periphery. In the middle, only horizontal lines appear in a circular region, while vertical lines dominate the surrounding area. The effect is achieved using two SVG masks—a peripheral mask and a center mask—that selectively reveal or hide the line sets. The code uses the native `document.createElementNS` API to construct SVG elements dynamically.
