This example demonstrates the basic structure of a VizHub V3 project by rendering the text “Hello World!” in a large, user-adjustable font size. It shows a blank slate starting point for the runtime environment, which supports continuous hot reloading and interactive widgets. The code exports a `main` function from `index.js` that receives a `container` DIV element and sets its inner HTML using template literals. Holding the Alt key and dragging the numeric value dynamically updates the font size in real time.
