This example demonstrates fundamental SVG drawing primitives within a fixed 960x500 canvas. It shows a circle with a thick black stroke, a diagonal line, and a path with relative coordinates, all rendered without fill. The code uses raw SVG elements (`<circle>`, `<line>`, `<path>`) defined in HTML, with a separate JavaScript file that only logs "hello world" and a CSS file containing an unused message class. The visual output is static, illustrating basic shapes and coordinate systems.
