This visualization reproduces a Sol LeWitt-style geometric drawing by layering horizontal and vertical striped rectangles, masked by three large symbols arranged diagonally. The masks reveal or hide portions of the line grids, creating interlocking shapes against a black-and-white canvas. Built with D3 v7, it uses `select`, `range`, and `symbol` to generate SVG marks, while custom mask elements with inverted fill colors alternate visibility. The code renders directly to the full window size, with no external data source, relying purely on procedural generation and SVG masking techniques.
