This example demonstrates basic SVG shape rendering with CSS-driven interactivity. It shows circles and rectangles positioned at various coordinates, grouped shapes with distinct stroke and fill styles, and a polyline path with rounded joins. The visualization uses raw SVG elements such as `<circle>`, `<rect>`, `<line>`, and `<path>` within transform groups, paired with CSS selectors that change fill colors on hover for circles and path elements. The code relies on the SVG DOM API for shape creation and traditional CSS styling for visual effects.
