This example demonstrates the fundamental structure of a VizHub V3 visualization, serving as a blank slate "Hello World" with a single line of text. It shows how the `main` function receives a `container` DIV element and renders directly into it using a simple HTML string with inline styling. The code highlights the new runtime's entry point, eliminating the need for an `index.html` file, and supports continuous hot reloading with interactive widgets, allowing properties like font size to be adjusted with Alt-drag for immediate visual feedback.
