This example demonstrates the foundational structure of an SVG graphic, starting with a minimal HTML page that integrates CSS for text styling and JavaScript for potential interactivity. The visualization itself is a simple SVG canvas containing a single circle element, positioned with an `cx` (center x-axis) attribute but lacking explicit dimensions or styling, leaving its appearance as a default black shape. The code specifically uses raw SVG markup, the `<circle>` element, and basic CSS rules, with no additional libraries or frameworks, as the title "SVG Fundamentals" suggests an educational focus on core vector graphics syntax.
