SVG Fundamentals
This example demonstrates the fundamental building blocks of SVG graphics, showing how basic shapes such as circles, rectangles, lines, and paths are rendered on a canvas. The visualization uses plain SVG elements within an HTML page, with no external libraries or data sources. It illustrates how properties like fill colors, stroke widths, and coordinate systems define visual output, with a path example using the `d` attribute to trace a polygon. The code serves as a minimal introduction to declarative vector graphics, relying solely on native browser SVG support for rendering.
