This example demonstrates how SVG shapes and colors can be controlled through CSS styling. The visualization uses an empty SVG container with dimensions of 960 by 500 pixels, rendered entirely through SVG markup. The stylesheet defines stroke properties for line elements, including a rounded line join and cap, with a teal color applied to paths. The example relies on plain SVG and CSS, without any JavaScript libraries beyond the bundled script, to show how visual attributes like stroke width and color can be declaratively specified.
