This visualization reproduces a Sol LeWitt art piece using D3.js, drawing 100 horizontal and vertical striped rectangles across the full viewport. The code applies two SVG masks—a circle-mask and a circle-mask-2—to show the grid pattern only within circular regions at the center of the canvas, while the outer areas remain blank. Built with D3’s `select`, `range`, and chained `join('rect')` operations, it renders with SVG and uses the `append('mask')` method to create the overlapping circular reveals.
