A simple SVG scene demonstrates basic geometric shapes and CSS styling. The graphic pairs circles and rectangles with distinct fill colors, including a group with a cyan fill and black stroke where a rectangle is rotated 45 degrees. Additional lines and a polyline path appear in yellow and blue with a rounded line join. The example uses raw SVG elements directly in HTML, with CSS selectors like `.lines` and `.lines path` to apply stroke properties, illustrating how SVG and CSS combine for static visualization.
