svg fundamentals
This example demonstrates basic SVG fundamentals by rendering a collection of geometric shapes—circles, a rectangle, and an ellipse—on a white canvas. The SVG markup defines each element with explicit coordinates and styling attributes, such as `cx`, `cy`, `r`, `fill`, and `transform`. It uses the native SVG API in plain HTML, with a white background rectangle and multiple black or unfilled circles positioned at various points, alongside a single transformed ellipse. The code directly illustrates how to construct and position primitive shapes in the SVG coordinate system without any JavaScript or external libraries.
