SVG fundamentals
This example demonstrates fundamental SVG shapes—circles, rectangles, lines, and paths—rendered directly within an HTML page using inline SVG markup. The code uses explicit attributes like `cx`, `cy`, `r`, `fill`, `stroke`, and `d` to control shape geometry and styling, with no external libraries or JavaScript logic involved. It shows how raw SVG elements combine to form a static vector graphic canvas of 960 by 500 pixels.
