SVG Fundamentals
This example demonstrates the fundamental building blocks of SVG graphics, including basic shapes, coordinate systems, and styling attributes. The code initializes an empty HTML page with an SVG structure, using plain JavaScript and CSS to render geometric elements. It does not load any external data or use advanced visualization libraries, instead showing how to construct and manipulate SVG elements directly. The rendering approach focuses on defining shapes inline within the SVG namespace, providing a hands-on introduction to the syntax and capabilities of the SVG format.
