This example demonstrates the minimal setup for a VizHub V3 visualization, rendering a simple "Hello World!" text message. It shows how the runtime environment enables continuous hot reloading without an `index.html` file. The code exports a `main` function that receives a `container` DIV element and directly sets its `innerHTML` with inline styles, including a large, adjustable `fontSize` value. It relies entirely on the native DOM API and the VizHub V3 runtime, with no external libraries or data sources involved.
