This is an abstract generative art piece that recreates a Sol LeWitt drawing using overlapping horizontal and vertical bands. A central circular mask isolates the grid of horizontal stripes, while an inverse mask reveals vertical stripes only outside the circle, creating a dynamic interplay of line and form. The visualization is rendered entirely with dynamically created SVG elements, using the standard DOM API `document.createElementNS` and `setAttribute` to build the shapes. No external libraries are used; the code relies purely on JavaScript and SVG masks to achieve the composition.
