SVG FUndamentals
This example demonstrates fundamental SVG rendering with a single green circle featuring a red stroke, positioned at coordinates (150, 150) with a radius of 50 on a 600 by 600 canvas. The code uses plain SVG elements within an HTML page, styled directly through attributes such as `cx`, `cy`, `r`, `fill`, and `stroke-width`. It serves as a minimal introduction to vector graphics in the browser, showing how to create basic shapes without any external libraries or JavaScript logic.
