This React and SVG example renders a grid of horizontal and vertical lines that form a circular composition. The code uses SVG mask elements to define two complementary circular regions, then maps over arrays to generate 100 thin rectangles in each orientation. The first mask uses a black background with a white circle to reveal vertical stripes, while the second mask uses inverted colors to reveal horizontal stripes. The result is a generative pattern that follows Sol LeWitt's conceptual drawing style.
