A generative SVG artwork reproduces a Sol LeWitt piece by filling a central circular mask with 100 horizontal bars. Two SVG mask elements define the visible circle and a second matching circle used as a cutout. The page constructs each bar as a `rect` element via the browser's `document.createElementNS` API, applying `url(#circle-mask)` to clip the stripes. Bars are evenly spaced at 20-pixel intervals, with a 10-pixel height, against a full-window black background, directly implementing the geometric composition in plain JavaScript and SVG, with no external libraries.
