Fork of Blank Slate with Hot Reloading
This example demonstrates the VizHub V3 runtime environment as a minimal "Hello World" starting point, rendering a static text string with a large adjustable font size. The code exports a `main` function that receives a container DIV and sets its inner HTML directly. It highlights V3's interactive widgets feature, where holding the Alt key and dragging a number in the editor enables continuous hot reloading. No external libraries are used, relying on plain JavaScript and the runtime's state management via `container` and `options`.
