SVG fundamentals
This example demonstrates the VizHub V3 runtime environment with a minimal "Hello World" visualization composed of styled HTML text. It shows how the `main` function serves as the entry point, taking a `container` DIV element and rendering directly into its `innerHTML`. The code uses a template literal to set a large font size on a div, producing static, centered text output. This serves as a blank slate for exploring the environment's hot-reloading capabilities, where values can be adjusted interactively by alt-dragging numbers in the editor.
