A stacked array of horizontal bands fills the browser window, with 100 rectangles of fixed height rendering as a full-screen vertical pattern. Each band spans the entire viewport width, creating a simple striped composition. The example uses plain SVG elements created via `document.createElementNS` and configured with setters for `width`, `height`, and `y` positions. No data source or animation is involved; the pattern is generated procedurally in JavaScript and appended directly to an SVG root element sized to the viewport.
