This example demonstrates foundational SVG drawing elements using a static, hardcoded scene of rectangles and circles arranged in a grid-like composition. The visualizations, including overlapping shapes and a diagonal arrangement, are created directly with SVG elements such as `<rect>`, `<circle>`, and `<svg>`, styled with CSS for a clean presentation. It shows how absolute coordinates and basic shape attributes like `cx`, `cy`, `r`, `width`, and `height` define the layout, while stroke and fill properties control appearance. The code serves as a concise tutorial on constructing vector graphics without any external libraries.
