SVG fundamentals
This example demonstrates fundamental SVG rendering by drawing a single circle element with explicit position and radius attributes. The code uses plain SVG markup within an HTML page, showing how the `<circle>`, `cx`, `cy`, and `r` attributes define a basic shape without any JavaScript or styling. A heading element accompanies the graphic to display text on the page. The visualization relies solely on native browser SVG support, illustrating the minimal setup required to create vector graphics, with no external libraries or data sources involved.
