{"version":"1.0","type":"rich","title":"5","description":"This example demonstrates the VizHub V3 runtime environment’s core workflow by rendering a single, large “Hello World!” message centered on the page. It shows how a simple `main` function receives a container element and writes directly to its `innerHTML`, using an inline style with a fixed font size. The code highlights the minimal setup required: no `index.html` file is needed, as the runtime injects the container and calls the exported `main` function. The example serves as a blank-slate starting point, illustrating how state management works through the optional `state` and `setState` parameters, though this instance does not use them.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/a588e78dc09f4d1e97c87aea471b8611?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
