This example demonstrates the VizHub V3 runtime environment’s interactive widgets and continuous hot reloading. The code exports a `main` function that injects a styled HTML div containing “Hello World!” into a provided container, with font size adjustable in real-time by Alt-dragging a numeric value in the editor. The example uses plain JavaScript and inline CSS, with no external libraries, to showcase the simplified entry point and blank slate starting point for building visualizations.
