This example reproduces a Sol LeWitt-inspired wall drawing by filling the screen with horizontal and vertical striped rectangles. It creates 100 rows and 100 columns, each 10 pixels thick, and layers them using two SVG masks to reveal a circular cutout where the orientations intersect. The visualization uses D3 v7’s `select`, `range`, and `join` to append SVG elements, while separate mask definitions with black and white fills control visibility. Rendering is fully SVG-based, with window dimensions driving the canvas size.
