Blank Slate
This example demonstrates the minimal setup required for a VizHub V3 visualization, rendering “Hello World!” in large text centered within a container. It uses the exported `main` function, which receives a `container` DIV and an options object, to set the container’s inner HTML with inline styles. The code does not rely on external libraries or APIs; instead, it shows the basic structure for continuous hot reloading, where state is initially empty and can be updated via `setState`. The rendering approach is direct DOM manipulation via `container.innerHTML`.

- There is no
index.html- that's what triggers the V3 Runtime - The entry point is the
mainfunction exported fromindex.js - The
mainfunction takes an argumentcontainer, a DIV that has measurable dimensions usingclientWidthandclientHeight - The second argument to
mainis an options object containingstateandsetState. - The state of the application is stored in
state, which is initialized as an empty object{}. - The
setStatefunction can be called with a function that uses the previous state to create a new state object using immutable update patterns. - For an interactive example, see Mouse Follower.
