{"version":"1.0","type":"rich","title":"activity6_question3","description":"This example demonstrates the \"Hello World\" of the VizHub Version 3 runtime environment, showing how a simple text output is created and rendered. It highlights the new development workflow, where a `main` function in `index.js` manipulates a provided `container` element, replacing the traditional `index.html` entry point. The example showcases continuous hot reloading and interactive widgets, allowing properties like `fontSize` to be adjusted live by Alt-dragging the number in the code editor. The core logic uses simple DOM manipulation via `container.innerHTML` to display text, emphasizing the streamlined, code-first approach of VizHub V3.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/9be24f943cbd4c55b94cb14f7947e5ae?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
