This example reproduces a Sol LeWitt wall drawing using an SVG canvas. Four equal quadrants display distinct generative line patterns: horizontal bands in the top left, vertical lines in the top right, diagonal hatching in the bottom left, and a rotated diagonal grid in the bottom right, each confined by rectangular masks. The work uses D3 v6 to generate repeated rectangles via `selectAll("rect").join("rect")`, applying spatial transformations like `rotate(45)` and `translate(-100, 0)` to create geometric variations. The full browser window serves as the drawing surface, with each pattern built from 100 iterated shapes.
