This example demonstrates the foundational building blocks of SVG graphics, showing circles, rectangles, lines, and paths rendered as vector shapes. The code uses the raw SVG API with elements like `<circle>`, `<rect>`, `<line>`, and `<path>`, each styled via attributes such as `fill`, `stroke`, and `stroke-width`. The path element employs the `d` attribute with absolute coordinates (`M` and `L` commands) to define a polyline. No external libraries are used; the visualization relies purely on SVG's native syntax within a static HTML page.
