This example demonstrates a minimal "Hello World" text rendering in the VizHub V3 Runtime Environment, showcasing the platform's live-editing and hot-reloading capabilities. The code uses a plain HTML `div` element with inline CSS styling, where the `fontSize` variable is set to 221 pixels. The main function directly injects the styled string into the container using `innerHTML`, with no external libraries or data sources involved. The approach highlights the simplicity of starting a visualization project within this interactive development environment.
