SVG fondamentals!
This example demonstrates the fundamental shapes of SVG. A blue circle and a red circle are drawn side-by-side, with a large rectangular outline framing the entire canvas in blue. The example also attempts to draw a line across the lower portion of the canvas. The markup uses raw SVG elements, including `circle`, `rect`, and `line`, with attributes like `cx`, `cy`, `r`, `fill`, `stroke`, and `stroke-width`. The overall piece serves as a basic illustration of SVG syntax and shape rendering in an HTML document.
