This example displays an empty SVG canvas with a 500 by 500 coordinate space, using the `<svg>` element directly within an HTML page. The markup includes commented-out examples of primitive shapes such as circles, rectangles, and paths, demonstrating how to specify geometry and styling attributes. The rendering relies on the browser's native SVG support, with no external libraries, and the commented code illustrates potential variations in fill, stroke, and path syntax for future visualization elements.
