SVG Fundamentals
This example demonstrates the absolute essentials of SVG rendering, starting with a minimal HTML page that provides a blank canvas for drawing. The code establishes the foundational structure for creating vector graphics, using no external libraries to show the raw capabilities of SVG and the DOM. It emphasizes the simplicity of defining shapes directly in markup, with the index.html file containing only the document skeleton and title. The example serves as a starting point for understanding how CSS and JavaScript can be layered onto SVG elements, preparing users for more complex visualization frameworks.
