This example demonstrates how SVG shapes and CSS styles combine to create static vector graphics. It shows circles and rectangles with distinct fill colors, including a group with a light blue fill and black stroke, alongside lines and a polyline path. The code uses raw SVG elements like `<circle>`, `<rect>`, `<line>`, and `<path>` within a `<g>` container, with scaling and translation transforms applied. CSS classes control stroke properties, such as color, width, line join, and cap. No JavaScript libraries or data sources are used; everything is defined directly in HTML and an external stylesheet.
