This example demonstrates the basic "Hello World" pattern for the VizHub V3 runtime environment, displaying a centered text message. The code exports a `main` function that takes a `container` DIV element and sets its `innerHTML` directly. The font size is a hardcoded number that can be interactively adjusted by Alt-dragging on it in the editor, triggering continuous hot reloading. This serves as a minimal starting point for building more complex interactive visualizations within the VizHub platform.
