{"version":"1.0","type":"rich","title":"Task1","description":"This example demonstrates the VizHub V3 runtime environment’s real-time feedback through a simple “Hello World” text display, where a numeric variable controls the font size. The code exports a `main` function that receives a `container` DIV and writes HTML directly into it using template literals. While the video shows Alt-dragging to modify the value, the code does not implement interactivity itself; it only renders static text with a fixed font size. The example highlights the simplified entry point and hot-reloading capabilities of the VizHub platform.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/4dded722cac347888137022fb36d2782?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
