This example uses SVG and CSS to draw a geometric composition of overlapping circles and rectangles. The shapes are rendered in two groups: one with translucency and default styling, and a second with black outlines and thicker strokes, demonstrating CSS class-based styling for lines and paths. The code uses raw SVG elements like `rect`, `circle`, `line`, and `path` within a React render, with transforms for scaling and positioning, and a stylesheet defining stroke colors and widths.
