This example introduces foundational SVG capabilities through a minimal HTML document, loading only an empty page structure with a title and no visible graphical output. The JavaScript logs “hello world” to the console, while the stylesheet defines a `.message` class with a 12em font size and centered text alignment, though no element uses it. It demonstrates the basic separation of HTML, CSS, and JavaScript files in a web project, using the native document object and CSS rules without any external libraries or data sources. The visualization gallery entry serves as a starting point for building more complex SVG-based charts.
