A full-screen SVG reproduction of a Sol LeWitt drawing displays a grid of vertical stripes overlaid with horizontal bands visible only through a circular mask, creating a stark contrast between masked and unmasked areas. The code builds the scene using the SVG namespace, generating 100 horizontal rectangles and 100 vertical rectangles, with a masked circle centered on the canvas revealing a 200-pixel radius region. The mask element, defined with a black rectangle and white circle, controls which horizontal bars appear, while the vertical bars remain fully visible across the entire viewport.
