Fork of Blank Slate
This example demonstrates the minimal setup for a VizHub V3 visualization, rendering a "Hello World!" message inside a container div with a large font size. The main function receives the container element and uses its dimensions to lay out the text, setting the HTML string directly via `container.innerHTML`. The code highlights the core V3 runtime API, including the exported `main` function and the immutable state management pattern with `state` and `setState`, serving as a blank slate for further interactive development.

- 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.
