This example recreates Sol Lewitt-inspired geometric art using D3.js, rendering a grid of horizontal and vertical rectangles that are selectively masked by overlapping symbols. The visualization displays five distinct shapes—including circles, crosses, and diamonds—positioned at the center of the canvas. The code uses `d3.select`, `d3.range`, `d3.symbols`, and `d3.symbol` to generate SVG paths, while SVG masks with inverted black-and-white fills determine which grid lines remain visible. The final pattern emerges from alternating mask states applied to the two perpendicular line sets.
