This fork of a Sol LeWitt art piece creates a striped grid pattern from alternating horizontal and vertical rectangles. Two overlapping masks, one positive and one inverted, reveal a central diamond symbol within the striped background. The visualization is rendered as SVG using D3’s `select`, `range`, `symbol`, and `symbols` APIs, sizing rectangles dynamically to the full viewport dimensions. The code relies on D3 v7 and applies the masks to shape the final composition.
