This example showcases basic SVG shapes and their styling with CSS, including circles, rectangles, lines, and paths. It demonstrates how individual shapes can have inline fill and stroke attributes, while groups can apply shared styles and transformations. The visualization uses SVG elements like `circle`, `rect`, and `path`, with cascading style rules from an external stylesheet. It also employs SVG transformations such as `scale` and `translate` to reposition grouped elements, and CSS classes to control stroke properties like line joins and caps.
