Basic
A minimal "Hello World" visualization demos the VizHub V3 Runtime Environment. The example displays a large, centered text string whose font size is defined by a variable, supporting continuous hot reloading via the runtime. It demonstrates the basic structure required for V3, where the `main` function exported from `index.js` receives a DIV container and sets its inner HTML to render the output. This setup acts as a blank slate for building more complex interactive graphics, with no external libraries or data sources involved.
