SVG fundementals
This example demonstrates the foundational structure of an SVG-based webpage using HTML, CSS, and JavaScript. The page renders a static HTML shell with a styled `.message` class for large text, though no content is currently injected. The code relies on standard DOM APIs and inline `<style>` tags, with no external visualization libraries or data sources. It serves as a minimal starter template for building interactive SVG visualizations, showing how CSS styling and an empty `<body>` can be extended with JavaScript-driven graphics.
