This example demonstrates fundamental SVG shapes and attributes on a simple HTML page. It shows circles, rectangles, lines, and paths, with comments explaining coordinate systems, fill colors, stroke properties, z-ordering, and path drawing commands like `M` (move to) and `L` (line to). The code uses plain SVG within an HTML document, with minimal CSS to remove default scrollbars, and no external libraries or data sources. The rendering approach is direct SVG elements, illustrating how primitives such as `<circle>`, `<rect>`, and `<path>` compose static vector graphics.
