This example shows a “Hello World” starting point for the VizHub V3 Runtime Environment, using a single exported `main` function from `index.js` that renders text into a provided container DIV. The code sets a fixed font size as a numeric literal, which can be interactively adjusted via Alt-drag during hot reload. It demonstrates the simplified entry point and real-time feedback model of VizHub V3, replacing the traditional `index.html` setup. No external libraries are used; rendering relies on plain DOM `innerHTML` assignment with inline styles.
