This example demonstrates a minimal interactive visualization setup in the VizHub V3 Runtime Environment, rendering a circular SVG logo with a blue background and the title "Rohith ICE 5". The visualization is built using the `main` function, which receives a `container` DIV and an options object with `state` and `setState`, enabling reactive updates and hot reloading. The SVG rendering is static, but the structure highlights the runtime's capability for interactive widgets with continuous development feedback.

AI-generated description

A blank slate starting point showing the "Hello World" for the VizHub V3 Runtime Environment, which supports continuous hot reloading with interactive widgets.

  • There is no index.html - that's what triggers the V3 Runtime
  • The entry point is the main function exported from index.js
  • The main function takes an argument container, a DIV that has measurable dimensions using clientWidth and clientHeight
  • The second argument to main is an options object containing state and setState.
  • The state of the application is stored in state, which is initialized as an empty object {}.
  • The setState function 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.
