This example generates a full-screen SVG that reproduces Sol LeWitt’s minimalist wall drawings. It creates a grid of 50 narrow vertical rectangles, each ten pixels wide and spaced twenty pixels apart, which collectively fill the entire browser viewport. The piece demonstrates the use of the Document Object Model (DOM) API’s `createElementNS` method to construct SVG elements directly through JavaScript, rather than employing a library like D3. The code iterates a loop, appending each rect to the SVG root, whose dimensions are set from `window.innerWidth` and `window.innerHeight`. The result is a clean, algorithmically generated abstract composition.
