This example demonstrates fundamental SVG rendering by creating a full-screen canvas filled with evenly spaced vertical stripes. The code constructs an SVG element using the raw `document.createElementNS` API with the SVG namespace, then iterates across the viewport width in 200-pixel increments to append thin rectangular shapes. Each rectangle is positioned with an `x` attribute and given a constant width of 10 pixels, stretching to the full window height. The result is a minimalist visual pattern that shows how basic SVG primitives can be dynamically generated and styled through JavaScript.
