This example demonstrates the use of SVG and CSS for styling shapes, highlighting how CSS selectors can apply presentation rules to SVG elements. The visualization is a functional, empty page that sets a monospace font and defines a class called `.highlighted` that turns text red, but no visual content is rendered. It uses a minimal HTML structure linking to a stylesheet, without any JavaScript libraries or data sources. The display is static, focusing purely on foundational SVG and CSS integration rather than interactive or data-driven graphics.
