{"version":"1.0","type":"rich","title":"FIRST_LESSON","description":"This example demonstrates the foundational setup of a VizHub Version 3 project, serving as a \"Hello World\" for the runtime environment. It shows a minimal HTML page that renders the text \"HELLOWORLD!\" inside a browser, using the exported `main` function from `index.js` as the entry point. This function receives a `container` DIV element and an `options` object with `state` and `setState` for immutable state management. Unlike previous versions, it requires no `index.html`, instead relying on the simplified `main` function structure. The example highlights the continuous hot reloading feature, where holding the Alt key and dragging numbers in the editor provides real-time updates to properties like font size.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/3ac4a13cf82d4d66a3f31b73e80c6fee?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
