This example recreates Sol LeWitt’s geometric wall drawings using D3.js, rendering a dense grid of thin vertical and horizontal lines across the full browser window. Two opposing masks, each containing five distinct symbols from D3’s `symbol` API, selectively hide or expose portions of the line grid, creating overlapping, patterned regions. The visualization uses `d3.select`, `range`, and `join` to generate 120 rectangles in each orientation, with SVG masks applied via `mask.append` and `attr('mask', ...)`. The result is a digital homage that blends generative code with minimalist art.
