Fork of Blank Slate with Hot Reloading
This example demonstrates the minimal setup for a VizHub V3 visualization, showing a static "Hello World!" message rendered inside a container DIV. It highlights the runtime’s hot reloading capability, where changes to the `fontSize` variable are reflected instantly without a full page refresh. The `main` function receives the `container` and uses its `clientWidth` and `clientHeight` for layout, while storing application state in an empty object and updating it via `setState` with immutable patterns. No external libraries are used, relying on plain JavaScript and inline HTML strings for rendering.
