This visualization reproduces a Sol LeWitt art piece using D3.js, displaying a grid of horizontal and vertical bars that are selectively revealed through two SVG path masks. The masks, created with the `symbol` function to generate complex paths, alternately invert their fill to hide or show different sections of the overlapping rectangles. The code uses D3’s `select`, `range`, and `join` APIs to efficiently build the SVG structure, with masks applied via the `mask` attribute. The artwork is rendered dynamically based on the browser window’s dimensions.
