This example demonstrates how SVG shapes and colors can be styled directly through CSS and inline attributes, using circles, rectangles, lines, and paths within a single graphic. It shows how fill colors, stroke widths, and line joins are applied both via presentation attributes and a linked stylesheet. The code uses plain SVG elements inside a `<g>` container with transforms for scaling and translation, while the `.lines` class in CSS configures black strokes and rounded line caps. No data source is involved; the illustration focuses purely on static SVG rendering techniques.
