This visualization reproduces Sol LeWitt’s Wall Drawing #370 using two overlapping sets of horizontal and vertical bands, each masked by a large geometric symbol. The first mask creates vertical stripes from 100 horizontal rectangles, while the second, inverted mask shapes horizontal stripes from vertical rectangles. Built with D3.js, it uses `select`, `range`, `symbol`, and `symbols` to generate the complex mask paths, and renders entirely as SVG, with dimensions matching the browser window.
