SVG Fundamental
This example demonstrates basic SVG shape rendering, showing circles and rectangles with varied fill colors, stroke properties, and dimensions. The code uses raw SVG elements like `<circle>` and `<rect>` within an HTML document, with attributes such as `cx`, `cy`, `r`, `fill`, `stroke`, and `stroke-width` controlling appearance. A large outlined rectangle with a blue stroke frames the composition, while a smaller yellow rectangle with a navy border provides contrast. The rendering relies entirely on native SVG markup without additional JavaScript libraries.
