SVG fundamentals
This example demonstrates the foundational structure of an SVG-based visualization, presenting an empty `<svg>` element within a minimal HTML document. The code establishes the essential setup for creating vector graphics on the web, with the SVG canvas ready to receive drawing instructions. The example uses plain HTML and CSS to define the page structure, while JavaScript is noted as the scripting language for future dynamic behavior. It serves as a bare-bones template, illustrating the core components needed to begin building interactive data visualizations with SVG, a powerful and scalable format for rendering shapes, paths, and text.
