This visualization reproduces a Sol LeWitt art piece as an interactive SVG composition. It shows a circular mask revealing horizontal and vertical striped bands, while a second inverted mask exposes the same structure in negative space. The code uses raw SVG APIs to create masks, rectangles, and circles without external libraries, generating 200 striped rectangles dynamically via nested loops. The rendering approach relies on SVG mask elements to layer and alternate visibility across the full viewport.
