This example reproduces a Sol LeWitt art piece as a generative drawing in the browser. It creates a grid of horizontal and vertical lines that are partially revealed through two distinct masks, resulting in an intersecting pattern of geometric shapes. The visualization uses D3.js version 6.6.1, specifically the `select`, `range`, and `symbol` APIs, to render SVG elements based on procedural rules. The code generates a hundred stripes in each direction and applies mask filters to alternate their visibility, producing a complex, layered composition that mimics the artist's systematic style.
