This example recreates Sol LeWitt’s geometric wall drawings using SVG and the Document Object Model (DOM) API. It displays a grid of horizontal and vertical stripes, masked by two overlapping circular regions that produce an inverted, framed effect. Two SVG `mask` elements, one with a black rectangle and white circle, the other with a white rectangle and black circle, alternately reveal the stripes within and outside the circle. The code generates 100 rectangles in each direction, setting their size and position programmatically.
