FIRST VIZ
This example demonstrates the VizHub V3 runtime environment through a minimal "Hello World" showing the text "vanakam da mapla!" rendered with a large, adjustable font size. It highlights the platform's continuous hot reloading, where holding the Alt key and dragging the numeric value in the code updates the font size in real time. The code exports a `main` function that receives a `container` DIV element and sets its inner HTML directly, requiring no HTML file setup. Interactive widgets enable this live editing experience within the plain JavaScript and DOM manipulation approach.
