This example shows basic shapes—a circle, rectangle, line, and path—rendered in SVG inside an HTML page. CSS styles the circle with a blue fill and black stroke, and a hover state transitions the fill to purple while thickening the stroke over 2000 milliseconds. The page uses plain SVG elements with inline attributes for stroke, fill, and coordinates, demonstrating fundamental vector graphics without any JavaScript libraries. It serves as a minimal starter template for building interactive visualizations with HTML and CSS.
