This example reproduces a Sol LeWitt-inspired drawing using only SVG elements. It shows a grid of horizontal and vertical lines confined to a circular mask, creating a clean, geometric composition. The visualization is generated procedurally with JavaScript, using the Document Object Model (DOM) APIs to create SVG nodes. A white circle on a black mask defines the visible area, while 100 horizontal rectangles and 100 vertical rectangles are drawn across the full canvas, with the horizontal set clipped by the mask. The code relies on native browser APIs such as `document.createElementNS` and `setAttribute`, with no external libraries.
