This example renders a minimalist visualization inspired by Sol LeWitt, showing a grid of vertical black rectangles evenly spaced across the full width and height of the browser window. The code uses the SVG API to create a single `<svg>` element with 100 `<rect>` elements, each 10 pixels wide and positioned every 20 pixels, filling the viewport. The rectangles are drawn directly with `document.createElementNS` and appended to the SVG, with no data source beyond the computed window dimensions.
