SVG Fundamentals
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.
