This example creates an abstract grid of horizontal and vertical black bars, generated using D3.js. The composition is layered with two SVG masks that apply geometric and symbol-based cutouts, revealing alternating patterns. The code uses D3’s `range`, `selectAll`, and `join` methods to efficiently build the grid, while `symbol` and `symbols` generate the mask paths. The result is a dynamic, self-contained visual piece that plays with positive and negative space, rendered entirely in SVG.
