This example demonstrates a minimal HTML page that combines CSS and JavaScript to render basic SVG shapes, including a green circle, a navy line, and a black polyline path. The page uses static inline SVG elements within the HTML markup, without any external libraries or dynamic data. CSS is applied via a style tag, and the SVG canvas is set to a fixed 500 by 500 pixel size. The visualization serves as a bare-bones template for exploring how SVG primitives compose a simple graphical scene.
