SVG Fundamentals
This example demonstrates the "Hello World" of the VizHub V3 runtime environment, showing how a simple `main` function receives a container and renders text directly into it. The code uses vanilla JavaScript with a template literal to inject an inline-styled div, setting a fixed font size of 217 pixels. It highlights the environment's interactive widget capability, where holding Alt and dragging the numeric value for `fontSize` provides continuous hot reloading and real-time visual feedback. The example serves as a blank slate for understanding the streamlined entry point without an `index.html` file.
