sample
This example demonstrates the VizHub V3 runtime environment, a blank starting point for interactive coding. The code uses a `main` function exported from `index.js` to render a numeric input field into a container element. By holding the Alt key and dragging the numeric value, developers can experience continuous hot reloading, adjusting properties like font size in real time. The example highlights the simplified entry point without an `index.html` file and showcases interactive widgets for immediate visual feedback.
