{"version":"1.0","type":"rich","title":"Activity6_Task3.4","description":"This example demonstrates the fundamental \"Hello World\" pattern for the VizHub V3 Runtime Environment. It renders a single line of text with a large, adjustable font size directly into a container element. The code exports a `main` function that accepts a container and sets its inner HTML with inline styling, showcasing the simplified entry point that replaces the traditional `index.html` file. The use of an integer literal for font size highlights the platform's interactive widget system, where holding Alt and dragging the value provides immediate visual feedback.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/8104f4cd2620425d900a02b89e7d650a?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
