The visualization reproduces a Sol LeWitt art piece using D3.js, rendering a grid of horizontal and vertical bands that alternate in visibility. Two SVG `<mask>` elements, created via a reusable `renderMask` function, selectively hide or reveal these stripes using symbol shapes—drawn with `d3.symbol` and `d3.symbols`—as the mask pattern. One mask uses inverted fills relative to the other, producing a contrasting interplay of lines and geometric shapes across the viewport. The artwork is generated entirely from code, with no external data source.
