This example reproduces a Sol LeWitt wall drawing as an interactive SVG canvas. It displays a central white circular mask over a field of 100 horizontal black stripes, with the circle acting as a window that reveals the full-width bars. The piece uses the SVG DOM API directly, creating a mask and rectangles via JavaScript, without any external styling. Each stripe is 10 pixels tall, and the composition fills the entire browser viewport, adapting to the window’s dimensions.
