This visualization reproduces a Sol LeWitt wall drawing using D3.js, rendering a grid of horizontal and vertical lines as SVG rectangles. Two masks overlay the composition, with one inverted, creating a contrasting pattern where the line grid is partially revealed or hidden. The code builds 100 spaced rectangles in each direction, then applies masks generated from D3’s `symbol` paths, which are transformed and positioned across the canvas. The rendering uses D3’s selection and join APIs to construct the SVG dynamically, with dimensions matching the browser window.
