A compact demonstration of SVG fundamentals uses overlapping red and green circles, an ellipse, and a thick red line to illustrate basic shape and path rendering. The example relies on native SVG elements such as `<circle>`, `<ellipse>`, and `<line>`, with minimal HTML/CSS for full-viewport display. A significant portion of the code is commented out, including a `<rect>` and complex `<path>` data, leaving only these core primitives visible. The rendering approach is purely client-side, using the SVG namespace directly within an HTML document, with no external libraries or data sources.
