This example demonstrates the minimal "Hello World" output for the VizHub V3 Runtime Environment, rendering a single line of text centered in the container. It serves as a blank slate that introduces the runtime’s core mechanism: the absence of an `index.html` triggers the V3 runtime, which calls the exported `main` function with a DIV element as its `container` argument. The code sets the container’s inner HTML directly, using an inline style to control font size and text alignment, with no external libraries or data sources involved.
