This example demonstrates basic SVG shape rendering with CSS styling. It shows circles and rectangles positioned directly on an SVG canvas, with colors applied through presentation attributes like `fill="red"` and inline styles, as well as a `<g>` group that applies a shared `fill="blue"` to multiple shapes. The code uses native SVG elements (`circle`, `rect`, `g`) with a `transform` attribute for translation, plus an external stylesheet for global page styling. No data source or dynamic behavior is present; all shapes are static and defined directly in the HTML markup.
