This example recreates Sol LeWitt’s geometric art by generating a grid of vertical rectangles across the full browser window. Each rectangle is positioned horizontally at regular intervals, with a quarter-width offset, while its height remains fixed at 500 pixels. The rendering uses raw SVG APIs, including `document.createElementNS` and `setAttribute`, to create and style the shapes dynamically. The code calculates spacing based on the viewport’s width and height, adapting the pattern to the display size.
