This example renders a static SVG illustration of a landscape with a sky-blue sky, green ground, and several geometric mountain shapes made from polyline paths. The code directly embeds SVG elements such as `rect`, `path`, `ellipse`, and `circle` in HTML, using CSS to set the background. It also demonstrates basic JavaScript string concatenation within an attribute, referencing a variable named `height` that is not defined in the displayed code. The visualization serves as a minimal starter template for understanding SVG drawing without external libraries or data sources.
