SVG Fundamentals
This example demonstrates fundamental SVG shapes—circles, rectangles, lines, and paths—rendered directly in an HTML page. It shows basic attributes for positioning, sizing, and styling, including fill colors, stroke colors, and stroke widths. The code uses plain SVG markup with no external libraries, manually specifying each shape’s coordinates and properties such as `cx`, `cy`, `r`, `x`, `y`, `width`, `height`, and `d` for the path. The visualization serves as a minimal reference for constructing vector graphics in a browser.
