This example demonstrates fundamental SVG shapes and attributes in a static 960×500 canvas. It shows overlapping red and green circles, a thick navy diagonal line, a horizontal path with rounded corners, and a black angular polyline. The code uses raw SVG elements—`circle`, `line`, and `path`—with inline fill, stroke, and stroke-width styling. Rendering relies on the browser’s native SVG support via the `svg` tag, with no external JavaScript libraries or data sources.
