This example demonstrates the placement and styling of basic shapes within a two-dimensional SVG canvas. It uses raw SVG elements, including circles, paths, and stroke properties, to create simple geometric compositions. The code utilizes inline SVG attributes such as `cx`, `cy`, `r`, `fill`, `stroke`, and `stroke-width`, along with path data `d` for drawing lines. Without external libraries, it relies on the native SVG API for rendering within an HTML page.
