This visualization reproduces a Sol LeWitt art piece using raw SVG manipulation through JavaScript, without relying on D3.js despite the title. It displays 100 horizontal and 100 vertical striped rectangles layered over a full-screen canvas, with circular masks creating a central viewing window where stripes intersect. The first mask reveals horizontal bands within a 200-pixel-radius circle, while the second mask inverts the pattern to show vertical bands outside that circle. The code builds the SVG dynamically using `document.createElementNS` and applies masks via `mask` and `circle` elements, rendering geometric abstraction through procedural loops.
