This example demonstrates how SVG shapes and CSS classes can be combined to create a layered, colorful composition with circles, rectangles, and a polyline path. The SVG markup uses basic geometric elements with inline fill and stroke attributes, while a separate stylesheet applies a green stroke with rounded line joins to the path and black styling to the `.lines` class. The rendering relies on pure SVG and CSS, with a group transform scaling the entire graphic and translate offsets repositioning elements for a stacked layout.
