This example demonstrates the creation of a dynamic SVG visualization that adapts to the browser window’s dimensions. It generates 100 vertical rectangles, each 10 pixels wide, positioned incrementally along the x-axis using a JavaScript loop. The code uses the raw SVG DOM API via `document.createElementNS` to construct and style the rectangles with a skyblue fill, and it logs the computed viewport size to the console. The visualization showcases fundamental SVG shape rendering with programmable layout logic.
