{"version":"1.0","type":"rich","title":"Activity6_tutorial3.2","description":"This example displays a large, centered message reading “Hello HTML!” using a minimalist layout. The page is styled entirely through embedded CSS, which sets the font size to 13em and centers the text horizontally. It uses plain HTML and CSS within a single file, with no JavaScript logic or external libraries beyond the basic document structure. The rendering approach is a static, unstyled browser default, demonstrating the fundamental separation of content and presentation in a web document.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/76f4b7bfdae0481e9d631879c68a6617?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
