This example generates an abstract, generative artwork inspired by Sol LeWitt using vanilla JavaScript and SVG. It creates 100 vertical rectangles, each positioned at increasing x-coordinates across the full browser window. The code uses the Document Object Model (DOM) API `document.createElementNS` with the SVG namespace to construct the elements, setting attributes like width, height, and position via `setAttribute`. The rendering approach relies entirely on procedural generation, with no external data source, producing a minimalist grid-like pattern of thin bars against a blank background.
